I know about back tension and "blind bale shooting".
Then do it
In all honesty you have to take your brain out of the shot IMHO the only way you can do that is blind bailing and using back tension, concentrate on getting the feel of the release going off and build that into muscle memory.
If you are using a wrist release then ditch it and get a good quality thumb release preferably one with no trigger travel so it will give you the surprise release.
I have switched over to the new Mag-Tek release and in all honesty you dont know when the magnet is going to break away and trigger the release.
