Your sample size is 1 for each of the 4 treatments. If it were any more than 1 you would be able to measure variance, which you cannot. If you would like more clarity in your data, id suggest running the test a couple times. Especially since your using a 13ci tank. I believe the LSET was designed for larger tanks (68ci) and would allow for more balls to be shot per treatment.
13 ci is a great shortcut, I would do the same, but id just suggest repeating the test a few times to make sure there isnt any variation. This would give you a larger "sample size" or replicates as they are called and would allow you to be more confident in any conclusion you make. I know you guys spend a lot of time on these things but i think it would be the best option to complete the test.
actually, no the LSET (Larson Standard Efficieny Test (as in Bryce Larson
)) works great on a 13ci tank. It gives numbers large enough to see variation when you make adjustments etc - but small enough to make it handy.
I'll pick up some more paint and when I do the tests on the Protege for reference I'll chuck some more paint through the G6R.
And yes, in the past I have done it a multiple times on the same gun. There just isn't variation. Any gun that's getting good consistency (which this G6R was) will produce very similar numbers repetition after repetition.
