PP-standard size of bets preflop

[Phill S]

ok, i know the 3BB rule, and i know its not right in most of the levels.

So, what do people opening raise preflop at what levels. so far ive been betting:

level 1, 75
level 2, 120
level 3, 150
level 4, 250
level 5, 500
level 6, 700

obviously, i push if im short, and ive never been at level 7 or above where i wasnt pushing due to the blinds simply being so big.

is this bad? should i bet bigger earlier? bigger later? smaller ever?

help appreciated.
