Theory
470 = 5 × 94, and 470edo shares the fifth with 94edo. Unlike 94edo, however, 470edo is only consistent to the 5-odd-limit. Using the patent val, the equal temperament tempers out 703125/702464, 823543/820125, and 1500625/1492992 in the 7-limit; 3025/3024, 4000/3993, 6250/6237, 19712/19683, and 117649/117128 in the 11-limit. It supports uniwiz and decimetra.
