I saw another thread that had some interest so I thought I'd just throw this out there. Here is a spreadsheet I made a while back for shot count and the like. It shows FPS, FPE, SD, ES and all that stuff. It has 3 columns and will generate graphs to the right for both FPS and FPS. Sometimes it helps to see what it looks like. Especially if you have an unregulated gun. I had a Marauder at the time so there are slots for hammer spring (HS) hammer throw (HT) and port size (VMS). Feel free to edit that out if it is distracting.
