202edo is [[consistent]] to the [[9-odd-limit]] with a flat tendency in harmonics 3, 5, and 7. It also has a decent harmonic [[11/1|11]], though it is sharp unlike the previous harmonics, with [[11/9]] barely exceeding 50% relative error. Despite this, it is most notable in the 11-limit, providing the optimal patent val for many temperaments tempering out [[243/242]] ~~(which explains why 11/9 is inconsistently sharp)~~.
