The location of the lowest point and the height of the club are different observations.
If your driver is hitting the ground before the ball, first establish whether the club touches the turf, the ball strikes low on the face, or both happen on the same shot. These observations require different checks. A ball flying low does not by itself prove ground contact.

Separate ground-contact events from low-face strikes in a practice set.
Overlap matters: a single shot can contain both observations.
The two events can overlap. Counts identify your pattern but cannot identify its mechanical cause.
Why driver ground contact and a low-face strike differ
A driver hitting the ground and a ball striking low on the face are related observations that can occur together, but they are not identical. A low-face strike may occur without ground contact, and ground contact does not describe the exact impact location. Record both events for each shot before looking for a pattern.
The sorter includes an overlap field because the same shot can belong to both groups. This avoids inflating the total number of affected shots. It also keeps the language precise when you later discuss the pattern with a coach or compare another session.
Also distinguish a ball driven into the ground from a club striking the ground. A topped or very low-launch shot describes what happened to the ball; it does not establish the club’s earlier turf contact. Record a visible turf mark and a face mark instead of grouping every low result together.

Use overlap to count the affected shots correctly
Suppose four of ten shots touch the ground, five strike low on the face and two do both. Seven shots have at least one of the events: four plus five minus two. Two have ground contact only, three have low-face contact only and three have neither event.
Changing the overlap changes the distribution even when the two main counts stay the same. The calculator rejects impossible combinations, such as an overlap greater than either group. This is a counting model; it does not turn the pattern into a diagnosis about tee height, ball position or attack angle.
The overlap input must describe the same sample as the two event counts. For example, do not combine yesterday’s ground contacts with today’s low-face strikes. Count neither-event shots too: they provide the comparison needed to see whether a change affects one problem or both.

Keep the next experiment narrow
Record tee conditions, ball position and strike marks before making a change. Compare a small set after changing one condition at a time. If both events become less frequent, that is useful evidence, but it does not prove which movement changed or whether the improvement will persist.
Use the driver delivery tool when you also have face and path readings. If the horizontal strike pattern is your main concern, the driver-contact article shows why an average can hide alternating misses. Keep the counts and actual shot observations together rather than relying on one headline percentage.
Make a repeatable setup note covering tee height, ball position and surface. A controlled comparison might hold two constant while testing one small adjustment at comfortable speed. Avoid making all three changes after a single miss; the resulting improvement would be harder to explain or reproduce.
Put the idea into practice
- Observe a short set and classify each shot as ground-only, low-face-only, both or neither.
- Enter totals and overlap from that same set; keep photos or notes of the actual marks.
- Repeat with one recorded setup adjustment and compare the four groups, not just ball height.
Will teeing the ball higher fix ground contact?
It may change the contact task, but it does not guarantee where the club travels. Record the original tee height and compare a small adjustment while keeping other conditions steady. Check both turf and face marks.
Is a low-face driver strike the same as hitting the ground?
No. You can strike low on the face without touching turf. The sorter keeps these events separate and subtracts their overlap so a shot with both events is not counted twice.

How to use the results and check the calculation
Start with the labeled example, then replace the inputs with your own observations or chosen comparison values. The controls show the accepted units and range. Changing a value updates the outputs and the linked diagrams throughout this article; each section also lets you adjust one part of the same example.
Either event = ground + low-face − both; neither = total − either.
The two events can overlap. Counts identify your pattern but cannot identify its mechanical cause. Where a visual compares values, it keeps matching units together. Exact numbers appear below the drawing so a schematic scale cannot be mistaken for a measured result.
