You do the math.

Basically, with most regular 12ish ft-lbs pumpers, the major pump strokes once you get past the first 3 or 4 are each the rough equivalent work of cocking a fairly powerful springer. Even a typical Beeman R1 takes about 40 ft-lbs.
Fascinating, it’s really the amount of effort it takes at each pump to get a diminishing increase in power. At each pump you have to fight that air volume already in the gun to get even more in? What a stupid system when you think of it. Lol
