You're absolutely right, Scot, that the Paradigm piston competes with the pellet...

...for kinetic energy. But the reason it works anyway is because the piston only moves about 1/200th as far as the pellet, therefore has an average speed only 1/200th as fast, and so (because kinetic energy goes as the square of speed) steals only (1/200)2 = 1/40000 as much energy for every unit of mass.

So even though the piston probably weighs ~200x as much as the pellet, it nevertheless robs less than 1% of the energy.
