Once again, this is clearly not impossible. I gave you myself as an example. Arguing why or why someone should not shoot lower than their maximum is not relevant to this discussion.
Actually I was trying to leave draw weight out of it. I said it was irrelevant after you brought it up. That was my point. It doesn't matter what you decide for a draw weight but after you have established it and the
only thing you change is arrow weight, it is without question impossible to raise or lower momentum without rasing and lowering KE. It is impossible to equalize KE and raise momentum simply by changing the weight of your arrow. The only possible way to accomplish this is as I explained earlier is to take 2 steps. The first is to put on a heavier arrow, thus raising both ke and momentum. The second is to lower your draw weight therby lowering ke at a faster rate than momentum. So in other words, lets say you have established your draw weight at 55#, for all the good reasons you mentioned. Knowing full well that you could pull more weight. Now at this point if you decide you want to increase your momentum and either hold your ke the same or lower it, it is not possible to do it unless you lower your draw weight. It is impossible to do it by changing arrows alone. But if you have decided that 55# is a good weight for you for all those good reasons, why would you want to lower it and give away both ke and momentum. The only reason it is even possible to do what you are suggesting is that you will give up ke at a faster rate than momentum but if you are comfortable with the 55# why give up either? It makes no sense to me. Of course you could do it, but to me that's why this is a theoretical. IMO it's simply not a realistic ooption.
Sorry, I don't believe that just because both change, that they are equal in importance when determining which is the best measurement of penetration potential.
But what we are discussing is your conclusion that because momentum changes at a faster rate with arrow weight than KE then momentum must be more important with regard to penetration. I'm simply arguing that because the resulting increase in penetration is exactly the same you can not logically conclude by this reasoning that either is more important. It would be just as logical to conclude that KE is more important because it only takes a small increase in ke to achieve the same increase in penetration as a much larger increase in momentum.
