Five limit beats seven limit

Petr mentioned temperaments where the 5-limit can be tuned more accurately than the 7-limit, so I'm listing some where the minimax 5-limit tuning is more than twice as accurate than the minimax 7-limit tuning, together with the ratio. Sometimes, as with ennealimmal, this doesn't matter, but for less accuracy it becomes increasingly important.

Interesting list. Many of these are not unexpected, as for instance dominant, sharptone, and flattone (alternative 81/80 temperaments, not as accurate as meantone). Similarly there are those that are more associated with 5-limit temperaments (garibaldi, diminished, mavila, ripple, sycamore) or with higher-limit temperaments (orwell, rodan, unidec, buzzard, kwai).

Probably the most unexpected one on the list is pajara; although the 5-limit srutal is also important, and higher-limit versions do exist, pajara is most often thought of as a 7-limit temperament.

Pajara was certainly expected by me; in fact I had in mind I might use 34edo as an example, where srutal, pajara, hanson and keemun are all living happily together, with srutal and hanson much more accurate than pajara and keemun. Since 612 is a lot less familiar to most people than 34, I would have thought ennealimmal popping up would be less expected. Similar comments for sensi and 65.
