I'm not going to argue the point of science / physics so I agree with your first part but not the last.
To make just a short reply my belief is the faster the bullet travels then the shorter margin you have for that node (sine wave) to enable an exit at close to the ideal timing of the muzzle exit.
As I said, I'm not going to argue these points. It's not the topic. Perhaps a thread on ballistics / bullets / barrels.... go to the Accurate Shooter Site and join the topics by Bryan Litz and close to that those inputs by the Berger Team yet alone then Eric Cortina who as a long range (ie 1,000 yard) shooter (Team Lapua) has on his topic of testing at 100 yards for long range. In our own ball park here in Oz the input on long range (1,000 yards) that HOF Stuart Elliott has made on various Forums when he had the time to comment.
I have done my own testing at home where I have the time to pick conditions and what I have said I believe is the case. I have never had consistent accuracy over a whole day of competition shooting with using the highest velocity accurate loads. Just my story sorry and from some others who have done very well over the years at competition target shooting.
BTW... Two comments that Stuart Elliott said to me personally many years ago... I have a .243W "shoot it in competition, the 6mm is a very accurate cartridge" and "shoot a .22LR of any description at long range and you will learn about wind reading" then to go with that also "Practise, it will make you a better shooter be it Target /Hunting /Varminting".
Very wise person as is his better half.
