Just a bit of usefull information for you here..
If you get to gold star which is the one down from platinum then pokerstars
have a satellite which costs 1500fpps and the top 25% of the people in the pool get entrance into the monthly platinum vip tournament which i believe is a 1 million dollar prizepool..
If you can earn 1500 fpps a month then id say that was a good goal to aim for if you feel confident of placing in the satellites.
If it were me i would aim for 3000 fpps. this way you get 2 bites at the cherry. They maybe other satellites into this at a lower buy in, im not sure on that 1 but i would probably go for the 1500fpp buy in and feel confident in qualifying.
This way goldstar is probably enough, but you may find yourself getting as far as platinum naturally by aiming for goldstar level and goingthat bit extra more.
Good luck regardless!!
