A very nice 55-tone adaptive tuning

This is a scale I cooked up while working on 55-equal. As a starting point,
I wanted a 1/5 comma meantone temperament comprising all the 15 major and 15
minor keys. Next, I wanted septimal intervals for each and all of them. I
calculated the exact position for 7/1 for each key. On the 14th fifth from
C, there is a wolf sized 718 cents, but no one should need to use it.
Finally, I wanted the scale to be quasi-cyclic with middle second intervals.
Attached is the result. Notice, that when modulating towards sharps by leaps
of fifths, you may use excellent JI approximations.

It is an excellent Maqam tuning, with 9 "commas" to the whole tone.
