How to read it

The box is the range that holds 90% of your shots (mean ± 1.645 × standard deviation). The narrower it is, the steadier you are. The × marks the average landing point, and the dotted line is your target line.
Standard deviation = the size of the spread. About 7 of 10 shots land within "mean ± standard deviation."
