The earlier you do CT after reset, the less disorganised the groups tend to be.
Early in the week, there's still plenty of people who just want to get in, get their carbontwine from the weekly, and get out. It's only later on that you tend to run into an overwhelming number of dumpster groups, either due to their failure to complete the place earlier in the week, or the fact that they're still farming the place for gear and are bored to death and not paying attention properly.
