age-graded time = time × factor · age grade % = 100 × open standard / (time × factor)
2025 road standards by Alan Jones and Tom Bernhard, approved by USATF MLDR on 10.01.2025; source commit 4aac673, male sheet version 27.07.2025. Exact factors for whole ages 5-100, men/women, 5 km, 10 km, half marathon and marathon only. No track, trail or interpolated categories. The factor sheet is used; three inconsistent seconds-sheet cells are documented in the preserved dataset. Percentages can exceed 100%; they are not capped or treated as a current world-record claim.
