Much depends on any riser brackets you're using or any other mounting plates. Really? I'd take the suggestions, which are good ones all by the way, and prop up your AP press to these heights and use the same chair you'll use for re-loading and cycle the lever a few dozen times. Then shim the press up or down a bit and try again. Tune things to YOU and YOUR needs. Not to ours. It really doesn't take a whole lot of time to buckshee up a rig to hold the press at various heights within the range of suggestions mentio
Even so I seriously suggest a work chair that has the pressure ram lift so you can fine tune your arm reach for specific days. I've found that if my arm is sore or a little achy or stiff for whatever reason it helps to adjust the chair height by up to an inch or a little more either way to suit me for the day.
