    The Elliott article (sound.au) very thoroughly explores the part that I handwaved past with the word "inefficiencies." H&H just sorta cut to the chase - the difference is due to the square exponent in I^2*R. Doubling the current and halving the resistance still doubles the power loss, because the square gives you double × double (×4) and then the R factor takes you back down by half, final result is ×2: double the losses in the winding resistance.

    Doesn't the "TD" in "TDPRI" stand for "Thread Drift"?

    ;D
