On hostage maps, the other objective is to kill all the terrorists. Remember that was your point in an Admin Abuse thread last year.....:p When there are a lot of good players online at a time, many times it takes it to the last 30 secs to get to the primary objective. That is, if the teams are balanced.

That's exactly right. That's why the % of team alive can be taken into consideration along with other factors such as frequency of occurrence. If the amount of enemy players alive is substantial, the only way they could've been alive this long is if they were baiting or hiding. The primary objective is rescuing the hostages. The secondary objective is killing the terrorists. If you can't do the first, you try the latter. If it's not possible for either then you're wasting everyone's time by lurking.

I calculated the amount of time needed to rescue hostages while running with a knife. The number is pretty substantial. It's something like 45-55 seconds while running with a knife from back of ct spawn. I wouldn't do it based on the game time for cs_ maps. Instead, it'd go based on their distance from hostages, distance among hostages, distance from rescue zone, etc. If they have no chance based on a distance x time calculation, or they're unable to kill the terrorists, they've failed the objective.
