His claim is that focii decay based upon the level YOU are.
My claim is that the focii is based on the SPELL LEVEL you cast.
Like if you have a level 80 focus of 50% and a lvl 85 focus of 45%, lvl 85 spells will trigger the 45% lvl 85 focus whereas anything under 80 (and possibly 81 or 82) level spells will use the 50% lvl 80 focus.
Would be nice to know how it works. I think I'm right as it explains why different focii trigger for different spells (or at least it seems that way)
