I was volunteering for the womens shooting event at Koko Head yesterday and I had a person having difficulty doing precise handgun shots, 2" target at 4 yards. Flinching, mashing the trigger, pushing the shots to one side, etc. I tell her the typical focus on the front sight, firm grip, slow even trigger press. Better but still mashing that trigger.
Then I tell her slow 2 second even press on the trigger, with just enough pressure to fire but not a feather more. Nails most of the shots in one ragged hole
I'm going to use that phrase more.
How's about "let the shot break as a surprise" from the Army Pistol Marksmanship text.
Same thing, but very effectively communicates
how the shooter can train themselves to mentally disengage from any expectation of when the shot breaks.
Just line up, and steady increasing pressure on the trigger, once started - it goes off when it goes off.
It's another good, time tested way of communicating the point.
Actually, remembering a bit better (I'm old), I believe the actual phrase in the text runs "... as long as the shot breaks as a surprise, it will be accurate."
