  • Page 42, Traffic Control Router
    • I have concerns with this design, so it's a bit of a rejig. Changes are as follows:
      • Chemical plant to Fusion plant: for this configuration, it'd use five tons of fuel. I can't adapt that.
      • Cockpit to Bridge: Cockpits only have 24 hours of life support.

    • The armour calculation was way off, I'd seriously recommend taking another look at this one - as built, it has like 14.7t of cargo space. I'd recommend tacking on a High-Burn Drive, but either way it's going to need new deckplans.

Fast Cutter (p. 40)

The Maneuver drive should be 3 tons. Based on the description of the vessel, maybe the intent was to use a higher tech drive with reduced space, it even that wouldn’t come up with the numbers described in the book.
 
Apologies for the delay, we had a spot of illness in the office - but this has been updated, simply re-download from Drivethru or our website for the latest version!
 
Page 22, Trade Shuttle
  • M-Drive should be MCr10.8.
  • Total/Purchase Cost should be MCr22.48, Maintenance Cost should be Cr1873/month.
I can't figure out how these numbers work. I came up with 0.9 tons based on 1% of the hull and MCr 9 for the 500% prototype cost as per High Guard. Any help would be appreciated.
 
Prototype is 100% + 500% = 600%.

10.8/6 = 1.8
I am not a mathematician, but that makes no sense to me. Cost per ton is 2 MCr so 0.9 tons would be 1.8 MCr. 1.8*500%=9 MCr.

I take the numbers on the prototype/advanced table to mean all adjustments are made from the normal base. It seems odd that the numbers would be additive and then multiplied such as 600% and 1100% rather than a simple calculation of 500%, 1000%, etc. from the base.

My calculations for other examples in High Guard (such as the Jump Shuttle and Express Boat) match the printed examples as do the original versions of most of the ships in Small Craft and Adventure Class Ships. Perhaps the rule intention should be reviewed and the calculations checked again before the new books go to print.

Like so much with MGT, a few concrete examples of how to use a given rule would help immensely. It sure would cut down on multiple interpretations of how a rule is to be read.
 
Experience tells me that me that an auditor should follow the copy editor.

The text as written is additive, not multiplicative.

You could check against any other examples in the two new spacecraft books, I won't really know until I get them for the Christmas basket.
 
I've always read 500% as 5X the 100% cost, not in addition to it. I'm fairly sure that's the intent. At least it was the intent in the update CSC.

(or... I could be wrong. I did write it that way for the CSC (with explicit multipliers) , but in High Guard, it is +100% for the Early Prototype tonnage, and that does mean double tonnage, so, maybe 600% and 1100% is the intent. It is written that way, but I'll have to differ to others on what was meant.)

I suspect the High Guard table should have been printed with x rather than + signs. I can't imagine 600% and 1100% was intentional...the formula is just too odd to be logical.
 
There's also a chance I've been reading Highguard page 71 (Updated version) wrong - or rather not reading it at all.

Where the Referee deems it appropriate, the same
Advantage or Disadvantage can be applied more than
once to a component, increasing or decreasing its
quality. All alterations are additive. For example, if two
+10% alterations are taken, the net modification is 20%.


I've always assumed, regardless of times applied, it was x1.1, then x1.25 for 2 advantages - even if the same - then x1.5 for 3. But no, if size reduction x3 is applied, it should therefore only be x1.3 rather x1.5. Hmm. Energy Efficient is a fun one too, because the subtractions are also 'additive' (that part I got), so Energy Efficient is 25% + 25% + 25% less power or (75% less power, one quarter the initial- that part I've been doing and the deep space bootstrap drive thingy seems to almost require it) but the cost should therefore only be x1.3, not 1.5. Which is consistent with the 'additive property'. If it was all multiplicative, the the reduction would be 0.75 cubed, or 0.421875 x the original power.​

Make sure to only recalculate per the description.
For example, when an Advantage or Disadvantage
increases or decreases the size of a component,
calculate the modified price based on the original size
of the item, not the modified size.


Okay, that I also missed. So, a size reduced x3 M-drive would be 0.7 x the original tonnage, and the cost would be 1.3 x the original tonnage, whereas I've been doing 0.7 x 1.5 which ends up being only 5% more expensive than the base price per unit of thrust... so I can see, in hindsight (not blinded by the formula), that perhaps that is not all that reasonable. So RAW, it gives and takes away, depending. Mostly it gives.​

Hmm.
 
Customization was specifically revised from the previous edition to try and eliminate any ambiguity, any deviance from the author's intent would be their fault.
 
I have looked at a number of recent ships in recent publications and all appear to support my understanding of cost calculations for customizations. One example being the Tigress in The Imperial Navy. Your initial post did catch many, many errors and I am grateful for that. But it also introduced new ones not consistent with previous publications. I hope Mongoose will soon correct these new errors in updated PDFs for the Small Craft and Adventure ship books.
 
Any feedback available from Mongoose staff regarding the cost calculation issues mentioned above? Will the latest two publications use a different model than previous publications?

Hmm.

I reckon that section was just written poorly: the 10% modifications refer to Size Reduction or Energy Efficient, not to the cost modifications that Advanced/Very Advanced components give you. So picking Very Advanced will cost you +25%, but picking Size Reduction twice will decrease size by 20% (additive), not 19% (multiplicative).
 
I am not a mathematician, but that makes no sense to me. Cost per ton is 2 MCr so 0.9 tons would be 1.8 MCr. 1.8*500%=9 MCr.

I take the numbers on the prototype/advanced table to mean all adjustments are made from the normal base. It seems odd that the numbers would be additive and then multiplied such as 600% and 1100% rather than a simple calculation of 500%, 1000%, etc. from the base.

My calculations for other examples in High Guard (such as the Jump Shuttle and Express Boat) match the printed examples as do the original versions of most of the ships in Small Craft and Adventure Class Ships. Perhaps the rule intention should be reviewed and the calculations checked again before the new books go to print.

Like so much with MGT, a few concrete examples of how to use a given rule would help immensely. It sure would cut down on multiple interpretations of how a rule is to be read.
Look at the rest of the table. Am I to believe that picking Advanced reduces the cost by 90%? Or that Budget makes a component cost negative credits? Or that Early Prototype does exactly nothing to tonnage?

It's written oddly, yes, and I'd've preferred it to be +400% and +900% respectively - it's neater - but if I'm going to write errata, I'll write it based on rules that exist, rather than rules that don't.

I maintain that your interpretation regarding how these calculations are made is wrong.

Let’s examine a couple of examples from High Guard (update 2022).

First a ship with a disadvantage: the Express Boat on page 158.

The J-Drive is Jump 4 (increased size). It does not specifically mention what line on the page 70 customization table that would be, but I think most people would infer that it is the budget line since increased size is a single disadvantage.

Base tonnage for the drive before any other calculation would be 10% of hull +5 tons (page 16) which would be 15 tons. The disadvantage increases the tonnage by 25%. 15*1.25 (for the disadvantage) = 18.75 tons.

Cost calculations are based off the original unmodified 15 tons of the jump drive. Final cost would be -25% of the base cost (a multiplier of 0.75). (15*1.5MCr)0.75 = 16.875 MCr.

Both Tons and Cost as listed on the ship record (page 158) match the numbers above.


Second up is a ship with advantages: the Fleet Courier on page 183.

M-Drive is Thrust 5 (energy efficient x3). No modification to base tons so that is set at 20 tons (400*0.05). Base cost is 40MCr. Final cost would be +50% of the base cost (a multiplier of 1.5). 40MCr*1.5 = 60MCr.

Both Tons and Cost as listed on the ship record (page 183) match the numbers above.

I agree that the rules are not written as clearly as they could be, but between the rules and an examination of the ship records, it is pretty easy to determine the intent behind the rules.


Now let’s look at the Trade Shuttle example in my original post that questions your calculations. Page 22 in Small Craft.

M-Drive is Thrust 1, Protoype (energy inefficient). No modification to base tons so that is set at 0.9 tons (90*0.01). Base cost is 1.8MCr. Final cost would be +500% of the base cost (a multiplier of 5). 1.8MCr*5 = 9MCr.

Both Tons and Cost as listed on the ship record (page 22) match the numbers above in the ORIGINAL pdf release of Small Craft. The new edition has inserted what I take to be errors provided in your original post. Your calculations do not match how numbers were calculated for any ship in any previous Mongoose publication.

Unfortunately, all recommended changes you suggested appear to have been inserted wholesale without fact checking by the Mongoose editorial team. As I mentioned, you caught many actual errors, but new errors have replaced previous correct information in some cases.
 
... Final cost would be -25% of the base cost (a multiplier of 0.75)...
Yes; the final multiplier is 1 plus all relevant modifiers, in this case -0.25.

... Final cost would be +50% of the base cost (a multiplier of 1.5).
And, again, the final multiplier is 1 plus the relevant modifier; 0.5.

Final cost would be +500% of the base cost (a multiplier of 5).
With respect, 1 + 5 isn't 5!

... Also, I wrote at least some of the errata in High Guard 2022. I'm running under the same assumptions.
 
With respect, 1 + 5 isn't 5!
Very well. 5, 1, and any others I used in the examples are simply short hand for 500%, 100%, etc. Mathematical terminology is not my strong point, but I somehow muddle through. The math works out the same with identical results:

15*125% (for the disadvantage) = 18.75 tons.
(15*1.5MCr) - 25% = 16.875 MCr.
40MCr*150% = 60MCr
1.8MCr*500% = 9MCr

I have never had an issue with the table. I asked my two adult children, wife, and a couple of wargamers to read the table and calculate the numbers for themselves. All interpreted the rules as I have.

You and I clearly see things differently, but yours is a new interpretation that has not been used in any previous Mongoose publication that I can find. The question remains as to whether your interpretation is used for these two new publications or if Mongoose will stick with all previous published examples. Mongoose could issue a ruling, but seems curiously silent on the subject.
