Maybe I'm dense, but what is the difference between putting marks every mile, then one at 3.10686 miles, and putting marks at multiples of 1609.344m and then one at 5K? Using decimals in each situation. Besides, ulitimately it comes out as (18425 for me) clicks on a Jones, so why does it matter if you get there with metric math or Imperial math?
I guess I don't see why either one is "better" or eaaier than the other. TomAtoe, tomaahto.
