Here is the list straight from Party:

All No Limit and Pot Limit Tables 4 PP for every 20 raked hands
All $.5/$1 and $1/$2 Tables 4 PP for every 20 raked hands
All $2/$4 Tables 6 PP for every 20 raked hands
All $3/$6 and $5/$10 Non Jackpot Tables 12 PP for every 20 raked hands
All $3/$6 and $5/$10 Jackpot Tables 15 PP for every 20 raked hands
All $10/$20, $15/$30, $20/$40 and $30/$60 Non Jackpot Tables 18 PP for every 20 raked hands
All $10/$20 and $15/$30 Jackpot Tables 24 PP for every 20 raked hands
All $50/$100 and $100/$200 Non Jackpot Table 28 PP for every 20 raked hands

So, if you play 1/2, that's 220/4*20 = 1100 raked hands for $10. At 2/4, that would be 733 hands. Silver level earns points 1.5 times faster, gold 2x.

Obviously, the big bump occuurs at 3/6. If you can play that level, it's 366 hands, at silver it's 244 hands. Still not great, sucky even, but you can see it's really geared for 3/6 and above, and people who have played a lot of hands. Or made a lot of deposits, as others have detailed.
