Yeah, that's what I thought (ca:10-30%). Think @dv8r and @July.Fourth knows much better since they done it a couple of times before. Also, there was a thread by @fmldotcom and @darthsidiuos about this. They got almost the same % stats.
If you're planning to PT further then don't apply any SKP, wait until you reach certain lvl or *. But be prepared to buy a couple of green boosters if you're planning to get them to 7* or 8*
