For my purposes, displaying actual scores within the range -4 -> 10 would be sufficient. the low end is already capped, and the high end could either just have a ceiling of 10 or a score of 10+.
I am occasionally a "someone is Wrong on the internet!"[1] type and my inclination to wade in is directly proportioanl to the perceived traction of the inaccuracy. Without such a heuristic the choices are: reply to all, none, or a random sample which result in "poor information", "needless pedantry", and " undefined behavior" respectively.
