Why four
The Number Was Not Chosen, It Was Discovered
The first version of the plot had two surfaces: cut grass and rough. That immediately caught the
obvious problems — heads that snagged, soles that dug — but it missed two failure modes
that turned out to matter more in this valley than anywhere else.
The first was bare summer ground. From late June, a lot of Fresno-area fairways go thin in the
landing zones and stay that way until the rain returns. On that surface a broad sole with generous
bounce does not glide, it bounces, and the strike climbs the face. Neither cut grass nor rough shows
that. It needed its own patch.
The second was the collar. Kikuyu is everywhere on Central California courses, and a kikuyu
collar behaves like nothing else on a golf course: it holds the ball up where you can see it, then
wraps the hosel and shuts the face on the way through. A club can be perfectly fine in tall fescue
rough and genuinely dangerous out of a kikuyu edge. That needed its own patch too.
Four patches, four readings, and the sheet finally matched what people reported back. The ladder
has not changed since 2013 apart from the irrigation schedule.
