how much does average rake % matter?

[Byrn]

Was browsing through my PT summary stats and noticed this:

Avg rake % for 3 Party Poker games (all with less than 10k sample size):

5/10 6 max: $1.45 / 2.49%
10/20 6 max: $1.83 / 1.64%
15/30 full: $2.46 / 1.13%

Now I know lower is better when thinking of avg rake as a % of pot, but how much better? I'm not sure how to think about the question to get the right answer.

It makes sense that with a lower avg rake, you could make the same bb/100 with less of an overall edge, but I'm not sure how to quantify this. Can someone point me in the right direction?

Thanks for the direction! Seems to be exactly the discussion I want to join.
