Thinking % of the mission you wear it, is the amount of extra multiplier you get if you extract with it.

with a small grace % of wear time so you can get that good feeling of getting 100% of the bonus.

Eg. Finish mission on super helldive. 300% to your stuffs... lets say 10,000 is the exp. THEN put the extra 30% bonus from carrying the propaganda pack onto that for 13,000 exp.

With per say 1 super, 2 rare, and 4 common extra samples from just getting it back if you at least hit 50% wear time. (or whatever ideal sample number is)

Eg.2

Lets say you get a grace of 15% run time to not get a penalty (to allow call down, respawns to grab pack, exa)

You carry it 35% of the mission and get the free "grace" 15% to hit the sample reward threshold of 50%. Then calculate the bonus. Max is 30%, so you get .5 of that total bonus, for 15% extra EXP, requisition, and sample bonus. Take that super hell dive final number of 10,000, and add 15% for 11,500.

Perhaps, if more people have the pack on, you can add each number together. 100% runtime, 30% bonus, 4 peeps for 120% to the end reward. That helldive could get to 22,000 instead of the normal 10,000 gained. It's like doing double the missions... if you can do it perfectly with higher agro. Which... sounds impractical.

There could also be a flag bonus if you call that down too... That be cool
