Some hitters have five swings and never know which one is coming. One round they square everything up; the next they can't find it, and they can't tell you what changed. The problem usually isn't any single flaw — it's repeatability. A grooved swing you can trust every time beats a great swing you can only find sometimes, because only the repeatable one shows up in a game.
Why repeatable is the whole game
Hitting is timing, and timing needs a swing that runs on the same clock every cut. If your swing's rhythm changes from pitch to pitch — a long stride here, a rushed load there, a different launch each time — then your timing is a moving target and you're guessing. The best hitters aren't the ones with the flashiest swing; they're the ones whose swing looks the same on the tenth cut as the first. Consistency is what transfers from the cage to the game.
The good news: repeatability is trainable, and it's often the easiest thing to improve, because it doesn't require a new move — just the same one, grooved.
What the camera reads
CoachVision measures swing-to-swing repeat across the swings in your clip — how even your launch-to-contact timing stays from cut to cut. It reads on both angles, and it needs two or more swings to exist, so a single-swing clip won't show it. That's the reason to film a few cuts in one clip when you care about consistency: the tracker compares them and tells you whether you're running the same swing or five different ones.
It also hands you a last swing contact frame alongside your representative contact frame, so you (and the coaching) can literally compare your final cut against your best one — a quick eye-check for whether the swing held up or fell apart as you got tired.
The honest boundary: "contact" is your hands' speed peak, not bat-on-ball, and the camera can't see the barrel or ball. So this reads the repeatability of your swing's timing, not whether you hit each ball equally well. But swing timing is the thing that has to repeat first.
The fix — groove one swing with No-Stride Swings
No-Stride Swings are the fastest way to make a swing repeatable, because they remove the biggest variable: the stride. Start already at your landing position — no stride — and swing with rotation only. With the timing element taken out, your turn has nothing to vary, so it grooves fast. Ten swings off the tee, trying to make each one feel identical to the last.
Once the no-stride turn repeats, add your stride back in small and keep the same rhythm. The turn you grooved comes with you.
Film three or four cuts in one clip, check your swing-to-swing repeat, then ten no-stride swings a round until one swing — grooved — is the only one you own.
