PA.....I understand .......but your PSE example is the same thing I heard when looking into the Ultra2 with it's 6 1/8 " bh .......and I found it no harder to shoot than my MQ-1 at the time ! I put 3 in the 10 ring on a Vegas target at 20 yrds the first 3 shots I ever shot one on......w/ someone elses bow !
I have no doubt that some folks can shoot short brace height bows very accurately and you definitely seem to be one of them however, as I mentioned earlier, it is not necessarily just the brace height but also the other factors that are related to said brace height that can potentially impact accuracy.
