Optimal ASB%?

[Caddy_4_Life]

Has this been discussed and did any conclusions come out of it? I used to have a 35% ASB and was showing a decent profit. I increased it over the last 10k hands to 43% ASB and I'm still showing a profit but not as much. However I highly suspect these results are not firm due to the limited sample size at 43%. What do you guys feel is the optimal ASB%?

If it helps in determining it, I have a 28/20/2.4 style game right now.
