The COPS is quite easy to set up once you get used to it.
BAS needs to be about 14 or more for a revvy, and about 6 - 12 with an egg.
To set up SENS start at 4 and increase it until it passes the cops test every time, now put it up another couple of points and your there.
Remember settings of any type vary from gun to gun, so just using someone elses settings wont necessarily produce the same results.
