Invented scales
Zi Wei scale
A version of the 2L 3s MOS using octave shrinking. Its intervals deviate very far from the harmonic series, but they line up well with the partials of a struck platinum bar, so it would be a useful scale for struck platinum instruments or for synthesized instruments with similar behavior.

100ed312/215
An equal-step tuning which divides 312/215 into 100 equal parts.
It is a microtemperament of rank 1, for no-7s subgroups. It could be approached as a no-7s 17-limit, no-7s 23-limit, or no-7s 73-limit tuning. It is similar to 295edt (see EDT).
