cannot kill based off math of who is left

Admins have said that using TTT math is the exception to the metagaming rule. Emphasis is my own.

5. Do Not Exploit, Hack, Metagame or Otherwise Avoid the Game's Intended Limits
This includes ghosting, metagaming, hacking, and exploiting maps. Ghosting includes sharing information with someone who would not otherwise know it, including staff. Do not try to escape the map bounds or exploit map bugs that provide an unfair advantage to gameplay. Do not team, which is aiding people you know are not on your team. Do not put your client to 3rd person mode. Do not intentionally crash the server. Do not abuse console commands to exploit the way ingame items work. An exception to the metagaming rule is that you may use the number of remaining living players to deduce the number of living traitors, but only once the game has reached a point where there are so few traitors or players remaining that you cannot be wrong.
