someone has suggested "half movement points" for BT units, yes? Round up half MPs, and round down quarters...
e.g.
Walk / Run / Sprint
3 / 5 / 6
4 / 5 / 7
4 / 6 / 8
5 / 7 / 9
5 / 8 / 10
6 / 8 / 11
6 / 9 / 12
7 / 10 / 13
7 / 11 / 14
8 / 11 / 15
8 / 12 / 16
etc.
affords the unit designer more options :)
