I did another test laminate today, same size, 60gram spread tow + 450 + 220, IN2

see video, this is how slack the bag was during infusion, before it was sucked dead hard to the stack..

I have had bags similarly slack before - especially on smaller pieces where it is easier to reduce the overall bag pressure with the resin coming in.  There is no leak there otherwise you would see the streaks of air shooting across the laminate surface.
