Recovering through API the %ilvl perfomance per encounter ID, and other filters

Hello everyone,

I’ve already found a way to calculate a character %perf by recovering 1 - (rank / outOf). But now I’m trying to recover the value of perfomance per ilvl that appears on damage-done/healing, but i’m finding some trouble.

Is there any entry point in the API to recover %ilvl or would I need to calculate it manually?

Thanks.
And btw, your API is just MONSTROUS, in a good way. It’s really fast. (:
