real equal beating not almost

Meta meantone if seeded with whole number integers will produce whole number beating . whether it is a whole number fraction of a comma seem insignificant.
it is the sound one wants. also metameantone allows for an infinite number of tones to be added.
It also allows each person to seed it how they wish , depending on the application all with the same property. in a sense it is a whole family of scales just like meta slendro or pelog.
there are an infinite number of them
what is gained by sticking with a whole number fraction in this case anyway? which is nothing more than an equal division of a just ratio. not what one would call a very consistent method to work with.
Conceptionally, if you look at it, the very idea is rather awkward. take the opposite- just ratios fractions of equal divisions or of an equal generator that leave some remainder.
talk about mixing apples and oranges.
And if you are interested in equal beating what is gained by having one that is 'almost' equal beating?

Kraig, you missed the point and turned this into a value debate when
it never was one. If it sits better with you 'politically', you could
turn my statement around and have it say that meantone tunings with
*exact* simple-integer beat rate ratios happen to *almost* be simple-
ratio n/d-comma meantones, and it would be all the same to me. I was
simply trying to expand on George's observation in a friendly,
participatory manner.

I agree completely but this is what George started with so I jumped
off from there.

So does Lucy tuning, or 1/4-comma meantone, or just about anything.
What's the point?

Absolutely nothing and you misread me if you think I think otherwise.

Not sure what you mean here.

Anyway, since it appears you're more interested in finding imagined
points of philosophical disagreement than in the mathematical
curiosity at hand, I'll just give the answer:

The fifth of metameantone is 695.6304 cents.

The fifth of 5/17-comma meantone is 695.6296 cents.

A difference of less than a thousandth of a cent.

To do better with a n/d-comma meantone, you have to go all the way to
452/1537-comma meantone!

You may rightly ask, who cares? Maybe only Joe Monzo does, since he's
attached to a particular way of drawing lattices of n/d-comma
meantones that doesn't extend to meantones more generally. But George
Secor brought up the observation (broadly speaking) and I thought it
would make an interesting point of discussion, a way to bring one of
the curiosities from tuning-math over here. I guess I'll know better
next time.

So just to clarify my position: There's absolutely no musical reason
I know of why anyone would prefer 5/17-comma meantone over true
metameantone. It's just an example of a curious mathematical
phenomenon that the two are very, very, very close.
