Where this club lands
The field is every iron in the database that publishes both of the chart's figures — every brand, not just Mizuno.
This set's 7-iron is 31° — 45th percentile, stronger-lofted than 55% of the 889 sets that publish one. The median is 32°.
Loft ladder against the field
Loft at each club in the set over the middle half (p25–p75) of every comparable iron set on record — the busiest rung here is built from 900.

A break in the line is a club the set does not publish a loft for — it is never bridged, because joining across a gap would draw a loft the manufacturer never stated. Every brand's name for the gap wedge is pooled into one rung, since only 25 of 917 sets publish two of them.

The 7-iron of every comparable iron set on record publishing both loft and lie — 889 of them, binned by density.
Offset
Mizuno JPX921 Forged · 7-iron — the leading edge sits behind the line of the shaft by the published figure, drawn to the scale marked and seen from the toe, which is the one view that shows offset truly: it runs perpendicular to the face, so a picture square to the face would have it pointing at you. The outline is a nominal iron — this database holds no head geometry — so the gap the arrow spans is the only measured thing in the frame. The dashed edge is the median of the 7-iron of 580 iron sets on record that publish one.

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.

- Stock shaft, built.Mizuno names no stock shaft for this club on the sources we hold, so there's nothing to link.
The site is in beta and the database is still being built, so expect gaps. Know something we don't? Help us fill it in — a link to where it's published is worth more than anything else you could send.
