I see on the bottom of your graph "22-24.5gr" of TAC. If I run 22gr of TAC not 24.5, my QL will show the same graph as yours. Try plugging in 24.5gr and not 22-24.5 and see what pressures you get.

I don't have the software, a friend ran that for me. But I think/hope you're right! That would take my propellant burn rate up over 91%.

Edit:

I just looked at another chart that shows 22-26.3 grains, and it's showing a peak pressure of 39k??? I wonder if it's giving an Average/Median pressure??
