I will set up stages and shoot all A's as fast as I can, get the hit factor calculator and see what it is. Then shoot it at a faster speed see what it is. Then drink a monster and try and crush the time. Funny thing is for me anyhow shooting it full speed tends to produce the higher hit factor. Playing around with stages in practice have taught me what my potential speed can be in a match. I have been using the practiscore app.
