“yo_eddy”Standard deviation is the square root of the variance.  Variance is the average of of squared difference from the mean (average) of all your data.  The calculation changes slightly if the data is a sample of a total population, but in this instance you are calculating the entire population (your 10 shot string)

This link has a pretty good explanation of SD, variance and the calculations for both


This was my second guess, lol, Think I’ll just let the chrony figure it out.
