On crunching the math, echidnic gives the best combination of range and efficiency rather than amity.

Add amity back in, but retain Echidnic

Unfortunately, basic 5-limit chords are quite complex using the [[leapday]] scale, requiring awkward stretches to play. The [[rodan]] mapping is probably more intuitive and has a wider range, but has the disadvantage of skipping a chroma on some of the transitions between columns, making it impossible to play the full gamut of each octave, and each octave is substantially higher up on the keyboard.

The expanded mapping fixes this, but now the chroma goes diagonally down, requiring an adjustment of playing style when doing chromatic runs.

The [[amity]] mapping is a good compromise between them, providing an even heptatonic scale while making the full gamut playable, with the chroma going in the correct direction.
