Callaway iron
The Callaway Big Bertha iron is an iron in 10 options from 18°–56°, offered with 2 stock shafts, RH and LH.
Built against the iron fieldpublished figures only
Where this club lands
Two separate readings, because a club is two products. Each field is every iron in the database that publishes both of that chart's figures — every brand, not just Callaway.
This set's 7-iron is 27° — 5th percentile, stronger-lofted than 95% 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.
Callaway Big Berthamiddle half of the field
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.

7-iron field: Loft × Lie
The 7-iron of every comparable iron set on record publishing both loft and lie — 889 of them, binned by density.
Offset
Callaway Big Bertha · 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.
Offset through the set, against the field
Callaway's published offset at each club, over the middle half (p25–p75) of every comparable set on record that publishes one.

Head geometry doesn't change with the shaft, so it's stated once. A blank cell means Callaway did not publish that figure — we don't estimate.
Callaway publishes offset in millimetres; the offset (in) column is that figure converted, and Callaway's own is in the column beside it.

Made-for means a version built for this club, not the aftermarket shaft of the same name — a different product with different specs. We keep them as separate records and never blur the two.
