Jump drive size reduction due to tech increase

[Theophilus]

Just learning the high guard 2022 design rules and I have a question regarding the tech advantage/disadvantage from page 70.

Beowolf free trader. TL12 jump-1, drive 10 tons.
Jump one becomes available at TL9, +3 advantage at TL12.
So I can take 3 size reductions at TL 12 and reduce the size to 7 tons. At 50% cost increase, or stack the advantages and 85%.

Also the "budget" category is not base TL, but "cheaper" design.that is, I can build a regular TL 9 Jump 1 drive, or a cheaper drive with one disadvantage

That sounds right.

Check out @Arkathan 's spreadsheet, it was how I started to figure out the rules. But yes, you are correct. Also, the size reduction adds are the only legal way to reduce a jump drive below 10 tons. But you get better space savings using reduced fuel cost.

At TL10 the Jump 1 drive gets 1 advantage.
Size 10 ton, 10% advantage is 1 ton. Drive takes 9 tons.
Fuel 20 tons. 1 advantage 5% reduction, fuel reduced 1 ton.
Either advantage is 1 ton.
On the TL12 Beowolf trader, 3 reductions.
3 tons drive or 15%/3 tons fuel.

Power plant, fusion8, at TL10 2 advantages.
So, increase power to 88
Reduce size 1.6 to 6.4 tons
Or use a smaller 7 ton plant with 2 advantages power 77?

It's the five tonne overhead that kippers the deal, at the bottom end.

I'm pretty sure it's the only point on the scale, where the numbers are on even keel.

There are other considerations, such as engineers to tonnage ratio.
