Shot String fps spread help..

[maddoghutty]

Hi guys I forgot on how to work out the fps spread from a shot string say I have done a 10 shot string and want to get the average fps from that string how do you do that again on the calculator or work out on paper if anyone can help it would be much appreciated. The reason I want the average fps is to put into the istrelock app which I want to set up correctly so it gives me accurate data if anyone has any experience with this Strelock please add your comments on your experiences with it thx.

For the average add all 10 together then divide by 10. For the spread take the slowest fps from the fastest.
