Ok, let’s break some hearts. Here’s a list of what SD you need to have based on your sample size to be fairly confident you have a single digit SD load.

If your sample SD for that string size is higher than this, you *may* still have a single digit SD. But this is the number you need to be as confident as possible (generally speaking).

Flame suit ready.

- 3 shots: 1.5 fps

- 5 shots: 3.2 fps

- 10 shots: 5.1 fps

- 15 shots: 5.9 fps

- 20 shots: 6.4 fps

- 25 shots: 6.7 fps

- 30 shots: 7.0 fps

- 50 shots: 7.5 fps

- 100 shots: 8.1 fps

Basically, if you shoot a sample size over your chrono and the SD is larger than that, you have a chance (% of chance depends how much higher the SD is) that your load won’t be single digit in the long run.

This doesn’t mean that SD’s at or below these numbers won’t be higher. It also doesn’t mean SD’s above this won’t be single digit.

This is just the maximum SD you can have for a given shot string and be as confident as possible that you have a long term single digit SD.
