The prettied-up dump I got looked like this...

Where "LoadAvatarHeight" returns size * 0.6f (confirmed through testing that each point of size difference is worth +0.6 range), and I suspect one of the two floats multiplied by "MultiMeleeRangeVars" is size again which would put the other typically in the vicinity of 1.2875... although it's not a constant so it may well vary (by race?). Dunno.
