Rakeback is actually much lower, because with the new system VPPs changed from 8 to 5 for each 1 EUR/USD of rake. I'm sorry for the inaccuracy, but this change was not reported by Pokerstars, I just discovered it talking with support (because yesterday they removed any way of tracking rake/VPPs in their software).
Long story short: that 24% is more like a 15%.
