I realize that the only way to accurately analyze the similarites
between one tuning system and another is to compare their interval
matrices. But I thought it would be "fun" (and historically
informative?) to present this simplified comparison anyway:

55-EDO 2/11-comma meantone

degrees exponent of approximate 3:2
between degrees ~cents =(3^x)/((81/80)^((2/11)*x)) ~cents
