Corrections

If a measurement is wrong, a price is stale, or a maker has changed a material, tell us at editorial@tig-buy.net with the sheet title and the line in question. We check against our bench notes and photographs and reply within five working days.

Substantive corrections are appended to the sheet with the date and a short note on what changed. Score changes from a retest are shown, not silently overwritten. Typographical fixes are made without a note. If we cannot substantiate a claim we made, we remove it and say that we removed it.
