Every value on these pages is either taken from a manufacturer source, derived from one by a stated rule, or clearly labelled as a BOXPLAY assessment. Where a manufacturer publishes nothing, we say so instead of filling the gap.
- Curves
- 22 with published geometry
- Profiles
- ProSharp + legacy families
- Hollows
- 10–40 mm spectrum
Three labels appear throughout, and they never blur into each other.
- Manufacturer fact — published by the brand, reproduced in their own wording, with a link to the source.
- Technical derivation — computed from a manufacturer fact by a rule we state, such as converting a hollow in millimetres to an inch label.
- BOXPLAY assessment — our own editorial judgement, only where a review has actually been made.
