Someone explained it in the comments for the last event like this..

"for (normal) cards, once you use 3 LP the card will have its level drop by 1 the next time you meet it. For (rare) cards, it's 4LP. For (Emergency) Mao, it's 6LP"

So if you're using the max amount of LP for that type of Live it'll hover around 2 levels until your cards are strong enough to do it with less LP
