Very interesting stuff, thanks for sharing.
Do we at all know why this happens? Seems like a weird phenomenon. Like what mechanic is it that makes suppression affect larger squads to a higher degree (if that's a correct statement)?
Incremental accuracy, which at first, should only matter if you were trying to suppress multiple squads.
The thing is, there is something else which matters as well.
New set of tests:
Test 1:
Testing the same MG34/MG42 against 1 model on the open. Results are the same as before with complete squads.
Test 2:
6 x squads of 1 model Cons behind a sandbag at range 20 against MG34. It takes ages (16 bursts).
Test 3:
Now this is the interesting part.
6 x squads of 1 model behind sandbag at the left (A).
JUST RIGHT OF IT, a 6 model Con squad on NO COVER (B).
1 model Conscript squad right of the 6 model squad in NO COVER (C).
1 x squad of 6 model behind cover (D).
T 3.1:
If i aim at the right most model of (A), the 6 man conscript squad will not be suppressed. EVEN if all the bullets are hitting the unit (2.00 acc (MG34) x 0.5 (cover)), which should be what matters for suppression AOE. I tested both, perfectly aligned (by cancelling a sandbag construction) and spread formation.
T 3.2:
Same situation but now i aim at (C) which is farther aside from (B), compared to (A). 1st burst suppress on (C), 2nd burst pin (as before) and at this point it also suppresses (B) as it should.
T 3.3:
1 squad of 6 models behind sandbag (D) and (B). Aiming at (D) doesn't seems to change the result (i suppress in 5 bursts) but (B) doesn't get suppress after 2 mags (12 bursts)
IMPORTART PART: Aiming at the squad OUT OF COVER, suppresses the squad behind cover in 2 bursts (normal 5).
Test 4:
MG42 (1% accuracy) aiming at (B) -no cover-, suppresses in 1 burst (D) -cover unit- as well.
This is something which doesn't align with what we know of suppression at all.
