Yet you keep losing this argument..so insulting yourself must be some next level big brain logic.
As I've stated previously, it is as simple as loading another 10 rounds & shooting 2 x 5 shot groups at the tuner setting you believe showed the best results with the 3 shot group. Simple, straight fwd 10 shot verification.I’m your opinion what would this test look like to finally put this to rest and who would have to do it? I’m assuming if a manufacturer did it people would disregard it as marketing.
If you really wanted know the truth about the final chosen setting, you'd do a 10 shot verification, not for me or anybody else, you'd do it for you & your results. If you don't verify, you're not doing yourself any favours.
