Well, we're all musicians (a slight exaggeration of my own abilities there ...), and nobody uses 10 beats to the bar, its usually 2, 4, 6, 8, 12 of quarter or eight notes. Irish slip-jigs go to 9/8 time, but that's just a jig in waltz time, sort of. Maybe Dave Brubeck and Roger Waters can stretch music maths to 5 or 7; but that's the exception.
An old mate of mine once compared metric and imperial units: "A pint of water weighs a pound and a quarter .. there - it even rhymes"
