CoreCtrl performance/battery tuning

Hey, I was wondering if anyone has already played around with CoreCtrl to see if they can further optimize for battery life/performance depending on the ppd power mode? This tool does seem to have quite extensive possibilities, but the big question is if it’s even worth it or if ppd is already dialed in so perfectly that you’d have to majorly sacrifice performance in battery saver mode to a usability-harming degree, or lower the batter life in performance mode even further to increase performance.
