What performance can we expect from a smoked Tetrix?

I applied a little motor theory to see what we would expect when a Tetrix is smoked. (See blog post) Maybe you motor experts can poke some holes in the reasoning.

On the assumption that a smoked motor has fewer windings that reduces kt,ke and R... the smoked motor shows a higher speed at a given torque, no change in the stall torque, higher currents at all torques . So long as you can supply the current, the motor will provide more power at a given voltage.

Huh? This seems counter to what we are seeing. We know the smoked motor climbs are a little slower. If the assumptions are correct, then the reason for the slower climb must lie with the series resistance in the motor circuit. The higher currents cause a corresponding voltage drop across the series resistance and the motor voltage is smaller.

See post for detail example.
