PokerRoom Rakeback vs Party

Does any player have any experience or knowledge of how much rake back they would need to receive at PokerRoom (skins) to be comparable to Party? It is my understanding that PokerRoom is calculated by contributed rake. Is this correct? Assuming a tight aggresive playing limits of $5-10 and higher who gets 25% at Party what would be a comparable percentage at a PokerRoom skin? Any ideas or rough figures would be appreciated. This is a link to how PokerRoom collects rake if this is helpful:

I found out that the above scenario works out to about 25% less at a PokerRoom skin according to one source and EuroBet is planning on going by contributed rake.

Why not do a 20% rakeback deal and clear the Hollywood Bonus

Yes I think that's a good plan. In fact, I don't believe there is a conflict joining Hollywood, EuroBet and Revolutionary (all PokerRoom skins) so hitting all the bonuses would be the likely plan.

can you clear that bonus and earn rake back at the same time?
