your settings look pretty good to me, most people run the sear on at 3 or 3.5 just because.
just fyi but i could never seem to get my c-off much lower than 30 or i would get dropoff around 15bps and have to raise the lpr to compensate. if your going for reliability might want to keep it more around 35ms so you can still shoot as smooth as possible. if youve got extra paint you can keep lowering it and shooting a quick string untill you start to get dropoff to find how low you can go.
and setting the TT tol higher than 20% the gun might start to get bouncy depending on your trigger pull.
