You are just being you and I don't want to get into the weeds with you.
As I stated earlier... If the difference can only be found under ideal clinical conditions, then the difference is moot in practical terms.
If you would like to buy the rifles, scopes and ammo in lots to test it all, then make a video that meets your standards of perfection, by all means go ahead and PLEASE send us all a link.
Keep in mind that people watching these videos have a short attention span and often a limited knowledge. They don't want to watch a 3 hour video that clarifies every miniscule point.
It's understandable that it may be uncomfortable to be made aware of the shortcomings in your methodology. If you don't like getting into the "weeds" don't make unsupportable claims. Insisting the difference is moot doesn't change a thing.
Further, it may not be a good idea to defend your videos that by saying that those who view them are unqualified to draw appropriate conclusions. It's like you're saying they're too unaware (dumb?) to do so. After all, who would agree "Here's a group so it proves what I'm saying" sounds like a good answer?
