Temperament "radar"

I've implemented Paul Poletti's "quality radar" in Scala 2.2u.
It's described in the article _Temperaments for dummies_ at
http://ourworld.compuserve.com/homepages/paulpoletti/papers.html
Naturally it's not restricted to 12 tones.
Go to Analyse:Tone circle or open it from the File:New:Temperament
dialog.

Does it show the combined error of major and minor thirds for each
step? How does it know which interval is supposed to be the
third--is it assuming this is the number obtained from the
corresponding "standard" val?

No it shows them separately, major thirds in red and minor thirds
in blue.

No, it just takes the nearest intervals to 6/5 and 5/4,
so there's no influence of the number of notes in the scale.

So they fail to be about triads anymore, even for some ETs.

You mean cases like 52, that's right. I'll see if I can
add another user option to make that choice.
