question about the running tracker

twikoff

anyone know why the available options for entering your run skips from 10 min miles to 11.5 min miles..
it seems that with the exception of that gap.. there is an available entry for about every .5 miles
but for some reason, there is a 1.5 min mile gap..

my typical 40 or 60 min session is more along the lines of a 5.75 mph / 10.5 min mile...

since i prefer to round down.. Im rounding all the way down to 5.2 mph / 11.5 mil mile...

Ive looked at some other calcs... and it seems alot of those have updates every .5 mm, with the except ion between 10.-11.5mm..
so i was curious what is special about that gap.

(yea, i know i could calculate it out myself and manually enter... i dont trust my treadmill calorie count, dont currently have a fitbit or any other type of counter, and might be a bit lazy )
