say I win 60% over 200 hu sngs with a std dev of .95 buyins, 95% chance I'm between XX% winner and YY% winner...

A win rate of 60% corresponds to a SD of sqrt(.6 * .4)=49%. After n tournaments, the SD of your observed win rate will be 49%/sqrt(n). One rough 95% confidence interval is 60%+-2 standard deviations.
