How we mark low-point on a mat

A method you can dislike and still verify. If we cannot show you the bruise, we do not get to claim a location.

The bay uses four plates. They are not fancy. They are firm, numbered, and ugly in the way orchard bins are ugly. Plate 01 is the gamer. Plate 02 is the first candidate. Plates 03 and 04 exist so a mark has somewhere to live while we argue. We do not hit two setups on one strip. Mixing bruises is how you invent a story that neither head actually told.

Contact tape goes down in a horizontal rail, not a stamp on the crown. We want the entry, the deepest eat, and the exit on one line you can photograph without kneeling in a mystery. The tape is cheap. We throw it away after a recorded swing. Reusing a strip is how a previous toe bruise becomes this swing’s “evidence.” Juniper will scold you, then Rhea, then Tomas, in that order.

The ball sits on a tic that we treat as zero. After the swing we measure the start of the scuff relative to that tic, in inches, with a small steel rule that has no logo. Behind the tic is early. On the tic is the iron we want on baked turf. Ahead of the tic is late — allowed for a driver, rarely allowed for a 7-iron unless the golfer is hitting a specialty shot they can repeat on command, which they usually cannot.

Depth is a separate number. We look at how far the sole crushed the plate, in millimeters, against a dry reference dent we recut on closed days. A shallow trail with an early start is still a fat shot. A deep trail with an on-ball start is a different animal — often a hybrid with too much width, or a wedge whose owner opened the face and then forgot. Both get written. Neither gets a single nickname.

We photograph the strip before we peel it. The photo goes on the session sheet with plate ID, ball model, and a one-line flight remark (“held window,” “nipped,” “excavated”). Hero swings get tossed. If you stripe one ball that does not look like the other four, it does not get a funeral. It gets the bin. Fitting to a hero is how shops sell you a head you cannot find on Sunday.

Mats lie if you let them. Foam that is too kind lets the sole sink and pretends a late bottom was flush. Our plates are closer to a July fairway at Apple Tree than to a plush stall. Golfers sometimes say the bay “feels harsh.” Good. Harsh is the point. We would rather a session look rude at 11 a.m. than send you into a baked afternoon with a mark that only lived on sponge.

The sheet is the product. You leave with paper. If a build happens later in the week, Tomas works from that paper, not from a memory of a swing he liked. Memory is how low-point walks. Paper is how it stays. If you lose the sheet, Juniper can pull the photo from the clay-colored box. That is the whole method: number the plate, tape the rail, measure the tic, throw away the hero, print the rest.
