11/10, the large neutral second, is an interval favored by Ptolemy. Three of them are less than 4/3 by the wizardharry comma, 4000/3993.
Coincidentally, the interval between the most common tuning frequency (A440) and the second most common AC electrical frequency (50hz) is exactly 44/5, or three octaves above an 11/10.
