If we knew exactly how to get past Jagex's bot-detection we would never get banned.
Different mouse profiles (cursor speed, click speed, etc.) for different accounts MAY affect banrate.
Implementing a "fatigue" system (the bots gets "worse" at a task over time to simulate fatigue in playing) MAY affect banrate.
Implementing custom walk paths instead of using WebWalking MAY affect banrate (most likely).
Checking woodcutting experience MAY affect banrate (probably not).
Point is, we don't know. We guess, but in reality, we don't know.
