SST: Persistent trait

[Till]

I'm starting a MI army now, but I have problems with Persistent trait. On the one hand it says it continues to roll the damage dice if armour saves are successful and on the other hand it says that the Persistent effect only wears off if there is a natural 1 or 2 rolled.

So I figured out 2 situations for a persistent weapons.

Situation 1: Plasma Ammunition against lonely Tanker

So my MI CAP NCO throws his Plasma Ammunition at a lonely Tanker bug in direct fire. He gets to roll 4xD10 (2xD10 with LZ 2”).
Now at the start of the next player turn how much damage dice do the MI player roll?

-> 2D10, because this is the base damage of the plasma Ammunition
-> 4D10 because he rolled 4D10 to attack the tanker
-> As much D10 as hits were scored.

second situation.

I throw the Plasma Ammunition in direct fire at a unit of 3 Grizzly Exos. I score 2 hits. Then 2 Exos will be hit with one hit. Regardless of they are succeeding the save or not. Who gets how many damage at the start of the next player turn?

->2 Exos, each 1xD10 (Cause 2 exos got just one hit each.)
->2 Exos each 2xD10 (Cause 2 exos got at least one hit and the Plasma Ammunition has 2xD10 base damage)
->2 Exos each 4xD10 (Cause 2 Exos got at least one hit and the Plasma Ammunition does 4xD10 in direct fire.)
->2 Exos each 1xD10 and 1 Exo 2xD10 (Cause the Plasma Ammunition does 4xD10 in direct fire and the damage dice get divided among the Unit.)

This questions were already discussed in another topic (link) but we came to no clear solution.

it states that you roll the weapons damage dice against each target....so, if the weapon has two damage dice you roll two damage dice vs each target. If you roll a one or two, then next turn you only roll one damage dice.
You don't recalculate for direct fire..... the persistent effect is just the weapons base damage dice.
Any other way of doing it is far too complicated.

E.g. the plasma bug takes 2d10 in persistant effect after surviving a 4d10 direct fire.
If a squad of warriors take a 4d10 direct fire , then each model that survives a hit is on fire and takes 2d10 in persistant effect, by the same token, if a squad of warriors ends up in a persistant artillery effect, then they each take 2d10 in persistant damage.
Look at it this way..... persistant effect represents being set on fire (or something similar). If you survive the initial blast then the effects of being on fire won't vary whether it's direct or indirect. A plasma bug hit by 4d10 direct fire is just as 'on fire' as four warriors who shared those 4 hits or walked through a persistant marker.
