One way to prove this one way or the other is with a downrange chrono test.
If the downrange velocity improves with an airstripper fitted, then I think that would be likely to be because of turbulent air being stripped. If the downrange velocity doesn't change but there's a perception that groups tighten, that's either going to be down to harmonics or imagination.
Having at one time played a flute, I wonder if harmonics could be disturbed by a cross wind.
I've tried shooting groups at 55 yards indoors with a Steyr LG100 which had an interchangeable muzzle brake without stripper, one with and a silencer.
After shooting ten shot groups with all three and one with a bare barrel I found the differences to be negligeble.
The placebo effect seems to work well in air gunning.
