WE need collective data - Test to help us all learn something

I will give this a try in the next coming week.

My hypothesis is that this will affect a portion of individuals significantly, but not everyone.

Interested to see the final results. Though I will say your test needs many repetitions to be statistically valid using 5 shot groups offhand.

If everyone repeats the test 5 times, you could have some real data worth analyzing and publishing to the academic community.
Agree - and then there is a fatigue factor that must be accounted for
