Huh that's interesting. So does a squad with less models get suppresses slower? Also, does veterancy on either unit (mg or infantry squad being suppressed) affect the time it takes to suppress? Because when mgs (his or mine) get wiped, they seem to suppress veteran infantry slower and when vet0 infantry go up against the same mgs they seem to still get suppressed fine.
I only know part of the mechanic and the results. Specially since there were tweaks on how suppression works. TBH i would had to reroll the tests.
Accuracy affects AoE suppression but not direct suppression generated per bullet.
Fixed a bug where firing at non-infantry targets would suppress nearby infantry. Now suppression platforms will only deal AoE suppression if the primary target is an infantry model.
IF i'm shooting at a conscripts squad behind a sandbag, does the scatter hit on the sandbag generate AoE suppression? This is what i'm not sure atm.
About the model count, there's a value called incremental accuracy which works with +2/+3 models. If you want to test it, load cheatcommands, make a squad invulnerable and put a conscript squad behind a sandbag and then do the same test vs Rifles/IS.
