Don't make the range icon too accurate. Like in EAW icons have 1 ft granularity, i hate it. There's too much numbers to interpret the range if you're occupied with the enemy. The less numbers in icon/range counter the easier it is to read.
Maybe 100 yard granularity to 300 yards, then 10 yard granularity from 290 yards.
In WB's we get 10 yard granularity under 200 yards range but usually it is so close to collision already
that there's no time to check the actual range, all info is based on visual information when close enough. It doesn't matter if it's D1.8 or D1.75 if you got the enemy in your sights
Also the granularity could be user defined. Both in setup for default setting and in-flight if you want to get more information for formation flying for example.
