Retest Comparison
A retest comparison is a follow-up swing recording measured against an earlier baseline swing. It checks whether a targeted change actually happened.
The retest comparison closes the loop that a baseline swing opens. After a defined period of focused practice on a specific change, the golfer records a new swing under matched conditions. They compare it directly to the original baseline. This is the step that turns "I've been working on it" into a measured before-and-after. It is also where the value of having saved a proper baseline actually pays off.
A useful retest comparison isolates the one variable the practice was meant to change, rather than evaluating the whole swing freshly. If the goal was reducing an over-the-top club path, the retest should primarily ask whether that specific number moved. It should not open a new investigation into unrelated aspects of the swing that were never the target.
Retest comparisons are also where a golfer discovers whether a change has genuinely transferred into their swing. Or it may only appear in slow, deliberate practice reps. That is why the most meaningful retests are recorded under normal swing conditions, not artificially careful ones.
Example
Six weeks after saving a baseline with a -7° club path, the golfer's retest shows -2° on the same launch monitor, filmed from the same camera angle. That is clear, measured evidence the targeted change is taking hold.
In SwingVantage Motion Lab
A Motion Lab retest is judged on the fault your One Fix targeted, not on every read. You get one plain verdict: improved, some progress, no clear change yet, regressed or inconclusive. The overall score still guards against a fix that made something else worse. If the angle or framing changed, it rates the comparison as weak or not comparable.
Frequently asked questions
How long should I wait before doing a retest comparison?
Long enough for the new pattern to have a real chance to take hold — often several weeks of focused practice rather than a single session, since one-off improvement can be temporary rather than a genuine change.

- Baseline SwingA baseline swing is a reference swing recorded before you start work on a specific change. It is the fixed point every later retest is measured against.
- Progress Tracking (Swing)Progress tracking records and reviews swing metrics over time, not just one before-and-after. It shows if a change is holding, improving, or drifting back.
- Swing Overlay ComparisonA swing overlay comparison syncs two swing videos, overlaid or side by side, at a shared point like impact. Differences then show without relying on memory.
