Effect of attack rating on DPS

[Mirana]

(I did a search and could not find anything, so please don't yell at me).

I'm trying to understand the exact implications of strength and attack on my damage (sorry, I'm an engineer, I need transparency).

I was looking at Yaolin's monk/warrior weapon dps charts. He mentions that:

"DMG ratio" = (dmg*2+Bonus)/delay &
"Max Hit" =(((OFFENSE+STR)/100)*DMG)+DMG BONUS

And I'm good with all that, it makes sense. Every 10 strength or 10 "offense" increases your max hit by one point of damage. But what I can't find is how attack rating impacts how often you hit in the higher end of your range. Obviously, more weapon skill and strength = more attack rating which means you will hit for your max (or near your max) more often. I understand it also depends on monster AC. Does anyone have the formula for calculating effective DPS, taking into account attack rating?

Please don't tell me to parse it, I've already looked at several parses. I'm interested in a formula. I like being able to calculate the exact dps increase I will get from buying a hero bracer, because I'm a nerd and it's fun to me.

Thanks.
