That is what I would like to see.  The arithmetic steps they used in working
these out.  That 1/3 comma is supposed to give pure minor 3rds. I can do it
on a spread sheet, but the spread sheet (not me) uses advanced math.  That a
certain comma leads to 19 tone ET.  Amazing that they arrived at this.
Curious to know what their step by steps were.      ---ric
