I've just made an ultimate PokerStars rekeback table based on a couple of old tables from different forums and an official StarsCoin table. It includes rakeback by step, cumulative total rakeback and cumulative rakeback by VIP status. Hope you find it as useful as I do
If you have any questions, feel free to ask!
Here is the link (don't know how long will it last)!
VPP per dollar of rake is adjustable. By default it's 5.5 on PokerStars, but if you play microlimit cash games or use currency other than USD it should be different (details here). Just replace 5.5 with your actual value, and the table should recalculate everything automatically.
Edit: The existing PokerStars rakeback system will soon be scrapped as this article indicates and replaced with something dramatically different. Many players received this email, which clearly states that we won't like these changes. Before that happens, my table remains up to date.
