Ok, so my co-worker (with a degree in physics) said (after many calculations)
that the Work is directly related to the Volume.
Assuming 6 small pistons pump the same volume as 1 large piston, it will take
the same amount of work.
Keep in mind, with 1 piston, half the time you are doing no work, and half the
time you are doing a bunch of work. So, you should test 2 large vs 12 small.
