	If I understand correctly, this generator size was chosen because it balances 10/7, which is 17.5 cents flat, with 6/5, which is 17.5 cents sharp, but in pajara 10/7 is always 17.5 cents flat, so there is no point in balancing it. With the same reasoning you can say that the tuning where 5/4 is eigenmonzo, with a fifth of 706.843 cents, is the 7-odd limit minimax, because it balances the two worst intervals – 10/7 with 7/4, which are both, again, 17.5 cents sharp/flat respectively. If you take the term "minimax" literally, i.e. "The tuning in which the maximal error of any consonance is minimal", you get that any tuning between them is also a minimax, because in all of them the maximal error is 17.5 cents – that of 10/7.

	I suggest labeling the tuning with eigenminzo 48/35 the 7-~~off~~ limit minimax, because that's where 6/5 and 8/7 are balanced. That's also what you get if you take the minimum of the [https://en.wikipedia.org/wiki/Norm_(mathematics)#p-norm p-norm (Wikipedia)] of the errors when p approaches infinity. I haven't checked but some other odd-limit minimax tunings may be changed too.

	:: I honestly don't see why everyone sees patent vals as so arbitrary. To me the patent val essentially is the edo, non-patent vals really just exist to define wedgies/ET joins and that's it. -- [[User:VectorGraphics\|VectorGraphics]] ([[User talk:VectorGraphics\|talk]]) 06:44, 23 November 2025 (UTC)		:: I honestly don't see why everyone sees patent vals as so arbitrary.

			::: There's a difference between an edo and its patent val; the val describes the corresponding rank-1 temperament. See [[EDO vs ET]]. Sometimes it's better to use the second-best approximation for a prime harmonic; for example, it's much better to use the 34d val than the patent val when using prime [[7/1\|7]] in 34edo. In the patent val all of [[7/6]], [[7/5]], [[9/7]], [[14/11]], [[14/13]], [[15/14]], and their [[octave complement]]s are inconsistent, while in the 34d val only [[7/4]] and [[8/7]] are inconsistent. The ratios between harmonics are just as important as the harmonics themselves, and even more so when one realizes that there's much more of them. Also, the 34d val is much more useful than the 32edo or 54edo patent val.--[[User:Overthink\|Overthink]] ([[User talk:Overthink\|talk]]) 09:14, 25 December 2025 (UTC)
