What is the best method of calculating variance, Extreme Search or just Stats?

I currently have several behavioral anomaly searches that report users exhibiting authentication behavior that is X number of standard deviations above their mean or just in the 9Xth percentile based on a baseline period of behavior. After reading George Starcher's blog entries on the subject of Extreme Search I am considering implementing those searches using that app, but I am concerned that I am losing precision because I can't say for certain that "anomalous" means three standard deviations above the mean. I would like to hear about other users' experiences doing the same and whether you think the migration is worth the effort.

Extreme search is "fuzzy". If you want precise traditional stats just do that.
