Not talking flex or paradox am talkin BENT.........
Lets say you're shooting an iron man,where you're limited to one arrow.That arrow(aluminum) gets bent....whatcha gonna do?
But thats pretty obscure...so lets say you have aluminum arrows and are just out stump shooting.One gets bent near the tip.......oh wait,this is stump shooting,the next arrow got bent in the middle......dang,this stump shooting is tough on arrows,the next one gets bent near the fletching.
Now you have 3 arrows,they all have bends....how does the location effect their flight?Remember,we're stump shooting...so the show must go on.So we continue to shoot them.......my original point was that we have witnessed bent shafts going to sleep downrange.They are being shot at the same rotation and same velocity.....you can plainly see where the shaft finds its equilibrium and starts to smooth out(go to sleep).
The advantage here...one that isn't availible to bullet shooters is that we get to keep shooting the same arrow.And they go to sleep at the same downrange point.Its not all that difficult to understand.......its dual plane balance vs single plane balance.Think,balancing a driveshaft vs balancing a flywheel.
Now does anyone here cast bullets?Do you want to explain why some weigh more than others.....same with swaging jacketed bullets....would you like to explain why there's differences?That would be real world experience.Physics and complicated computer models leave a little to be desired when study'n certain flight characteristics.
Just sayin,using physics to explain certain phenom's is kinda like using statistics.The results can be skewed.
