Some local buses boast, on the back of the bus, that the service is 'up to every 7 minutes'. While I understand what is meant, the phraseology troubles me in a nagging way.
'Up to 8 per hour' would work, in that it is up from, say, 4 per hour. Whereas 'every 15 minutes' is up from 'every 7 minutes', numerically, but not in the sense intended.
Obviously what underlines the statment is You won't have to wait more than 7 minutes for a bus, at least at the busiest times.
(I think I may be late for my basket-making class - must rush.)
