It doesnt matter how long you play for in these cash ring games or tournament games. For Cash ring games. You'll notice that it says for NO LIMIT games it's atleast a $1 dollar rake to get 1 fpp point, Now consider how PS gets that $1 rake. It takes an amount equal to 20 dollars in the pot for them to achieve the $1 rake, which in turn gives you 1FPP. Now if you only see like a 10 dollar pot or 19 dollar point. You wont get the FPP. For example SNGs $5.50 give you like 3FPP points right when you buy in. Bottom line is. If you want to get FPP points for EACH hand you go into, Make sure the pot exceeds $20, Everyone involved in the $20 pot recieves 1FPP.

Hope that helps
