just fyi: the 3 units were as closely packed as the game lets me do it without stacking them on top of each other by hand. i doubt ANYBODY, EVER does that.
1st burst: MG starts to attack left squad
left squad: suppressed
middle squad: moving through
green cover so one AoE suppression of a single burst was not enough to suppress them
right squad: too far away to be affected
2nd burst: still fires at left squad (obviously, because first model loss was in left squad)
left squad: model lost
middle squad: suppressed through AoE effect
right squad: still too far away to be affected
At this point rifleman squads got very close, because MG42 was used without spotter and did not used all of its range.
3rd burst: MG switches to middle squad (next model loss occurred in the middle squad)
left squad: still crawling
middle squad: got suppressed, but already in grenade range
right squad: started to get suppression through AoE effect, but still not enough to actually get suppressed. Already in grenade range too.
If in same situation player would position MG to secure area without green cover and started to shoot middle squad - all three squads would be suppressed at the start/in the middle of 2nd burst - not in grenade range. I'm not even sure if spotter would be needed in that case.
So, in your "recent replay of blob of Rifle/IS/cons being able to a-move and crawl from the far end of mg42 fire area till grenade range" we see:
1) MG used without spotter (did not used its max range)
2) MG autofiring on unit on the left side and there is HUGE distance to unit on the right side (so these units were not in a "blob" for each other)
3) one of attacking unit was moving through green cover at the moment when MG was firing one of its bursts
Is it replay Esxile asked for? IMO it is not.
So what are you, guys, actually trying to discuss?
