Standard Deviation (STD) is in essence the quality of your data, a high # is means your data has a high variance, and the closer you get to zero, the more precise your data.

It is an important number, but if you look at your fps spread, than you do not need to concern yourself with it as much, especially since a lot of shooters tend to speak in terms of velocity spread.

Make sense?
