It is at Ozan Yarman's preferred size of about 382 cents for perde segah, and is almost exactly the size of the major third of 22edo, being 0.007 cents flat of 7\22. It could conceivably be used to tune 22edo by ear, as a cycle of 22 of these intervals fails to close by [-103 -22 0 22 22⟩, about a sixth of a cent, and 96/77 could be tuned by taking a 12/7 up and an 11/8 down.
