Well we may have to get some clarification from the folks at Stern, but I’m fairly sure that you need to claim a team up to maximize the award. For example using Wolverine (double damage) and Colossus (double scoring) I beat Juggernaut buy hitting both team up shots twice each then cashed out a 60-70 million point mode score. I’ve never come close to that type of a score without hitting those shots during the mode while lit (looking at an average of 16-30-ish million with no team up bonus)
Again, I may be wrong, but i’m pretty sure you need to claim them to take full advantage of the benefits.
Oh yeah, the BOOM button will kick in a team up if hit during a mode, moving from left to right I believe Tim said somewhere before.
Anyway, that’s my theory…
