I see that I can get my standard deviation BB for a certain sample size, which relates to my BB/100. My question is how can I use EV BB/100 to better approximate an expected winrate long term. It doesn't seem possible that EV BB/100 would have the same standard deviation as BB/100 since it removes all-in luck from the variance equation. I'm no math whiz, but my guess is that if a player was a winrate that is +/- 1BB/100, then if you used his EV winrate it might be say +/- 0.5BB/100.

The only other part of the variance equation would be related to what you flopped/turned/river BEFORE getting all in. A good example happened to me last night where a player slow rolled me with AA and not much money was on by the turn when my KK became KKK and we got all in. Also a factor would be how many times did a person get a very lucky outflop, ie set over set or AT hits trip tens when you have AA.
