Good question, not sure... Though to be honest I bet it only really comes into play with pretty experienced players anyway, in which it's just a source of info. A lot of beginners don't even seem to realize they can get volley details there, like shooting time. Obviously many figure this out eventually, but calculating specific ranges tends to be important only in advanced play.
Anyway, not really sure what to do about this just yet, though I agree it would be nice to have. Maybe others will chime in here? (Or I'd have to ask on Discord xD)
Personally I actually use it mostly for the volley info, since I care a lot about especially the total matter consumption, and sometimes total energy or heat. If I'm out of range for some weapon(s) to fire then I'll just use 'v' and examine the results, but I don't care about ranges quite so much in melee/out of combat. If I do what I want to know is how close an enemy is to spotting me, which pretty much only matters if you have a modified visual range, in which case you can toggle your utility to see the difference being animated and figure it out that way
(you'll sometimes see me doing this on stream...)
