Warm up strokes should never hurt your mental game, quite the opposite. I agree with everything PJ has said so far, along with the other instructors. One critical thing is counting strokes; that sounds more like OCD than pocket billiards to me. It's not 3 times and then GO because you're setting yourself up to get tensed right when you have to be fluid.
I don't recall ever seeing someone play an inch-perfect game without warm up strokes. Not repeatably at any rate. The players who most often just bend over and bang away are bar players who gamble their b!tches against your cue (for those who remember that story, I just can't get the audacity out of my head).
1 stroke or 4 isn't what's important. It's the last chance to make sure you're doing it right. Not second guessing either, just make sure you have the right path, CB aim point, and speed. If you make better shots without the warm-up then you're probably tightening your grip at the last moment in anticipation.
