Hang in there LittleLebowski - this is where it gets interesting - some of us have tried various presses but I have yet to see a scientific chart of the mechanical advantage listed for each reloading press. This is what your quest boils down too. you want the greatest work done with the least pressure applied to you damaged flipper. That is what this will tell us.
Found this,
calculating mechanical advantage of a press, measure the distance of the arc when you cycle the handle the end of the handle divided by the distance the ram moves at the same time ie; 30" divided by 3.5" of ram movement = 8.57 to 1 ratio?
As the leverage is a variable the mechanical advantage changes constantly through the swing of the arc of the handle movement, I think their formula is too simplistic. That's where the actual measurement of force applied to the handle in correlation to force applied by the ram comes into it's own.
I mean if your feeling flush you can buy one of these
