Bow damage formula?

[bcbrown]

I realized I forgot to filter out crit hits from the max hits column. Not gonna re-upload the chart, but here's str, dex, max hit.

239  144   74
162  144   67
196  89    71
197  153   71

Seems clear to me that the max hit calculation uses str, not dex. It doesn't look like the formula Goregasmic posted fits, though. My archery skill is 238 and offense is 245, btw.
