Now that we have a bunch of PP options (prat and advanced pp's) Which "number" do you think is better. You have prat #1 - PER number, prat #2 sheet style, prat #3 velocity number,prat #4 impact and advanced pp cramer number. I know that all of these are variations on a theme but they differ enough to make a difference. Has anyone studied one vs the other?
