The field is every driver in the database that publishes both of the chart's figures — every brand, not just Mizuno.
Across every option: this club's loft from the 38th to the 70th percentile, and length at the 33rd percentile.
The cloud is every driver head option on record that publishes both loft and length — 2,024 of them, binned by density.

Head geometry doesn't change with the shaft, so it's stated once. A blank cell means Mizuno did not publish that figure — we don't estimate.
Where this club's published fitting specs sit among comparable clubs — never how good it is.
