It would be nice if at least one of the Tremstats signature styles (http://stats.tremulous.net/tremstats/us1/player_getsig.php?player_id=1) would display efficiency, not just Kills and Deaths. Alternatively, the Deaths display could show just the number of deaths by enemy instead of total deaths. Since damage/death caused by turret or tube does not give the other team points, including them in the sig deaths gives a false picture of how much a player is hurting his team.
You're only saying that because your stats suck. :P
locking this, feature requests for tremstats go on the project page http://projects.mercenariesguild.net/projects/tremstats
