"Joseph Henry's first discovery was that the power of a magnet could be immensely strengthened by winding it with insulated wire. He was the first person to make a magnet that could lift thirty-five hundred pounds of weight. Joseph Henry showed the difference between "quantity" magnets composed of short lengths of wire connected in parallel and excited by a few large cells; and "intensity" magnets wound with a single long wire and excited by a battery composed of cells in series. This was an original discovery, greatly increasing both the immediate usefulness of the magnet and its possibilities for future experiments."

I think the root idea is that as long as the total copper is a constant, then the parallel design of the Double, Triple, etc.. passes more current with less voltage required. The no load speed seems not to be effected by what goes on at low rpm. The Triple SUCKS AMPS at low rpm much more than the Double and I would assume it would suck even less with the Single. By adding Armature Current Limiting I "filter out" the excessive low end current and keep the top end power with the parallel winds and it's low resistance.
It's hard to disagree with something you literally ride... the no load didn't go up from Double to Triple as long as the total copper was the same.
I should have "stuck to my guns" because my first "guess" seems to be what I actually experienced. (no change in the no load speed)
