Merge request

When considering whether 1ed125c is identical enough to 4ed4/3 to merge, I compared the harmonic approximations of both:

Approximation of harmonics in 1ed125c
Harmonic 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
Error Absolute (¢) +50.0 -27.0 -25.0 -36.3 +23.0 +6.2 +25.0 -53.9 +13.7 -26.3 -52.0 +59.5 +56.2 +61.7 -50.0 -30.0 -3.9 +27.5

(I wrote 4ed4/3 as 8ed16/9 to make comparing mapping easier).

The mappings of 9, 12 and 16 are different.

1ed125c has a meaningfully better 4, 5, 11, 17 and 18.

4ed4/3 has a meaningfully better 6, 8, 10, 14, 15 and 19.

I think these tunings are similar enough that they can be merged without having to mention these differences, especially given the mappings are nearly all the same.
