I have expanded my Squidoo page about tuning systems

Hi all,
I have expanded my Squidoo page about tuning systems (no scientific research, just a gentle introduction).
http://www.squidoo.com/tuning-systems

It was interesting to draw some 'pie charts' of scales: this reminds me of a discussion a few months ago about upon which bases should "cents" be defined.
Drawing pie charts naturally suggest 360 or 3600, or even 2\pi times some power of 10 :-)
Just as a trivia, a natural third would be 115.894 'degrees' and a natural fifth 210.586 :-) (3/10 of their measures in cents)
All criticism welcomed! Something has been conceded to the commercial aspects of the Squidoo stuff, of course: this is known a priori.
Many thanks.
Best wishes,
Claudi

No 360edo page as yet, and as for pi, there's always this:

A. G. Pikler published a comprehensive survey of Logarithmic Frequency Systems in J. Acoust. Soc. Am. *39*, 1102 (1966).
He made an error in the Droebisch's angular values for the fifth and twelfth: the correct values are
210 35' 11" and 570 35' 11" in the reference below, also by A. G. Pikler.

One might consider tuning units used by commercial synths-- 768, 1024, and 2048 notes per octave, IIRC, have
been used, the latter two as subharmonic series.
