Thanks. I did intend the 31-tET approximation for Arabic, not Persian,
scales, so the large discrepancies are to be expected. Mohammed
Gharib says, on his web page, that Persian tuning could be considered
a subset of 43-tET, so perhaps we should look at that. In any case,
thanks for the info above, that really helps. I have serious qualms
about Anooshfar's ratios, though: they seem "cooked". Since you'll find 25
and 25*2^n in the denominator of some ratios, but 5 or 5*2^n is not in the
denominator of any ratios, this tuning system requires that one perceive
ratios of 25 directly, which I find impossible. Anooshfar seems to be yet
another victim of high-number low-prime mentality.
