Total Distance in a Driver Fitting
Total distance adds estimated roll to carry. The engine keeps it as context, but it does not let rollout outweigh carry, dispersion, launch, and spin.
What is Total Distance?
The full shot distance including carry and estimated rollout, most useful when driver or long-club rollout matters. For a fitting, the important part is how this number connects to the rest of the shot pattern, not whether it looks good by itself.
| Field | Meaning |
|---|---|
| Technical definition | Total Distance is the calculated final distance from the launch point to the ball’s resting position after carry, bounce, and roll. |
| Common launch monitor labels | FlightScope: Total Distance; TrackMan: Total |
| Typical unit | yards/metres |
| Role in Smart Golf Fitting | Supporting rollout context |
How does Smart Golf Fitting use Total Distance?
Total distance is accepted as an optional field, but the current driver engine leans more heavily on carry and flight-window evidence. Total distance helps describe rollout potential and sanity-check whether a low, running ball is being overvalued by the simulator.
- Provides rollout context beside carry distance.
- Helps explain why a long total number may not be the best fit if carry or direction is weak.
- Supports consumer reporting without becoming the primary ranking signal.
Which related launch monitor metrics should be checked with Total Distance?
Total Distance becomes useful when it is read beside the numbers that explain its cause or its outcome. These relationships are what stop a fitting from chasing one attractive number while making the full shot pattern worse.
| Related metric | How the relationship works |
|---|---|
| Carry Distance | Carry is the air distance; total adds estimated rollout. The driver engine gives carry more weight because rollout can vary heavily by surface and simulator assumptions. |
| Descent Angle | Descent angle affects rollout. A shallow landing can inflate total distance, so the engine checks carry and direction before trusting the extra roll. |
| Spin Rate | Spin changes rollout as well as carry. Low spin can add roll, but the engine checks whether it also hurts launch, carry, or control. |
| Ball Speed | Ball speed shows the energy available; total distance shows the final simulator estimate. The engine checks whether total came from real speed or simply predicted rollout. |
| Launch Angle | Launch angle changes the carry-roll balance. A low launch may produce a big total number but still be a risky fit if carry or direction suffers. |
| Offline Distance | Total distance is only useful if the ball is playable. A long shot that finishes well offline is treated as a control problem, not a better fit. |
What can be misleading about Total Distance?
Total distance is more model-dependent than carry because rollout assumptions depend on ground firmness, landing speed, spin, and slope.
What does the engine do when Total Distance looks unusual?
A big total-distance number can hide a flat flight, excessive rollout estimate, or poor direction. The engine treats it as useful context, not the whole answer.
First check
Check whether total distance gains come with excessive offline distance or too shallow a descent angle for the intended club.
Fitting principle
The engine looks for agreement across the full shot pattern before changing the recommendation. If the related metrics do not support the same story, the report stays more conservative.
