Data gather: team power

Was changed it seems. I some how missed this post (and the one you linked) in my searching earlier today but:

Gives a possible updated one

CHANCE = (LIMIT * MASTERY) / (MASTERY + DECAY)

Old: LIMIT = 1 & DECAY = 100

This seems reasonably accurate based on my current masteries.
