Starting at the bronze level on 1/1/06 you would need to play:

1500 raked hands ($300 in tourney fees) to make the silver level

You get the silver level benefits immediately including the FPP bonus. You need 2500 more FPP to get the gold level but you get a 50% bonus so this means 1,666.67 raked hands ($333.33 tourney fees) for a total of 3,166.67 raked hands ($633.33 tourney fees).

This gives you the gold level which comes with a 100% FPP bonus. You need an additional 6000 points to make the platinum level so that would be 3000 raked hands ($600 tourney fees) or totals of 6166.67 raked hands ($1233.33 tourney fees).

From zero to platinum takes 6,167 raked hands or $1234 in tourney fees.

Once you’re at the platinum level, you get a 150% FPP bonus so maintaining platinum status would require just 4000 raked hands.

The math:

1500 raked hands with no bonus = 1500 FPP
+ 1667 raked hands with 50% bonus = 4000.5 FPP
+ 3000 raked hands with 100% bonus = 10000.5 FPP

4000 raked hands with 150% bonus = 4000 * 2.5 = 10,000

Note, this is for the pot limit, no limit, and 2/4 and higher limit

Someone check my math with ya?

It seems like attaining and maintaining platinum status wouldn't be all that difficult if you were doing it professionally.
