PP & PS points calculation

[spigge]

Hi!

Trying to figure out which site is better considering just points. So did little calculation anyone care to comment if I am way off or something

let's say I play 20k hands in a month. SilverStar is easily accomplished I got it this month quite easy so I assume I have it in calculation. Not so sure about equivalent in PP.

Party Poker about 44% raked in limited data in 2/4 SH
20000*0.44 = 8800 raked hands
(8800/20)*6 = 2640 partypoints
I quess 2x500 deposits per month is safe? so extra 2000 points
total 4640 partypoints
(4640/50000)*100 = 9.28% for iPod nano in party store

PokerStars 38% raked for $1 in my data for 2/4 SH
20000*0.38 = 7600 raked
7600*1.5 = 11400 stars points
(11400/16000)*100 = 71.25% for iPod nano

What I calculate wrong? They can't differ so much or can they?
