Tempering out the wizardharry comma doesn't produce the porcupine temperament- tempering 250/243 does- that said, the effect is somewhat similar in that tempering it out divides 4/3 into an equal-stepped tetrachord |

4000/3993, the wizardharry comma, is an unnoticeable 11-limit comma with a size of roughly 3.03 cents. It is the amount by which a stack of three 11/10 submajor seconds falls short of the 4/3 perfect fourth. Tempering it out means the 4th is divided into an equal stepped tetrachord, however, it does this by means equating a stack of two 11/10 submajor seconds with 40/33 rather than by equating a stack of three 6/5 intervals with a 16/9 interval as in the Porcupine family of temperaments.
