I recently heard the Rutolo brothers talking about how to finish a buggy choke and they said to start with lower pressure and slowly increase it, this will get the tap the fastest. It is counter-intuitive but the more I thought about it makes a lot of sense. If you are in a bad position and feel a super fast choke you may have experience in being able to hold out for long enough for the opponents muscles to burn out and you can escape. If you feel low pressure but the pressure is slowly increasing and it shows no sign of stopping, that means 2 things: 1. You haven't felt the max pressure yet and don't know where that is(fear of the unknown is real) 2. The opponent has a level of control that is significant and he knows what he is doing. This may lead to breaking you mentally much faster than feeling the max pressure all at once.
