Trail dump
Most Merrimack golfers leave weight on the back heel a beat too long. The pad timestamps the dump. If that peak is late, the face is already a passenger.

The feet load before the club is allowed to speak
G-Force Bay sits in a mill brick bay at 875 Elm. We read ground reaction on a granite pad — trail dump, lead brace, center-of-pressure wander — and only then argue about the bag. Wrist shops start at the hands. Stance shops start at posture. This room starts under the spikes.
Lead brace
The front foot has to accept the dump without collapsing the inside of the heel. Ice-month hardpan in January punishes a soft lead worse than April mud.
CoP path
Center of pressure should migrate, not hop. A hop on the heatmap is a jump, not a shift. We print the path before anyone talks shaft.
The mill argument
Loft is gossip until the pad is honest
Elm Street golfers arrive talking about a 7-iron that “just sits down.” They have already bought a grind, a shaft, a lesson. The pad usually shows the same story: trail heel hanging on, lead inside rolling, a CoP that never crosses. Changing the head on that pattern is painting a mill window while the floor joists still sag.
We built this bay because New England ground is a liar. January is granite. April is river silt. A load that looks athletic on hardpan becomes a stall in mud. If we do not map the feet on both seasons, the bag we hand you in March is a costume for November.
The granite slab under the sensors is bored into mill brick. It does not bounce like a gym mat. That is the point. The force-time curve you leave with is the one your spikes will meet on Intervale clay and on frozen fairways off Route 3.
Load tickets
Golfers who arrived talking clubs and left talking heels
We keep the loud quotes on paper tickets, mill-style. Full notes live on the pressure-notes wall.
I came in from Goffstown convinced the driver face was the villain. Mara showed the trail heel still glowing at 70 percent after the hands had already thrown. We did not touch the head that day.
January pad and April pad were two different people. Ellis made me come back after thaw. The mill bag only went out once both sheets agreed.

875 Elm, Suite 11
Mill brick, granite pad, brass door
Park in the rear lot off Stark, not on Elm itself. The freight elevator still works; the passenger stair is faster. Look for mill-red paint on the Suite 11 lintel and the heatmap bars on the glass.

Ask the mill for a pad window
Sending the form does not freeze a slot. June answers from the brass ledger, usually on the next open mill day.
