An age multiplier and a bodyweight coefficient solve different problems. Before comparing age-adjusted results, establish what quantity the age multiplier was applied to: a lifted total, Wilks points, DOTS points or another score.
What this site actually displays
The existing module applies a stored age multiplier directly to the lifted total. For clarity, the redesigned result is labelled “Age-adjusted total (legacy table)”. It is not labelled an official McCulloch competition score. The adjustment does not automatically include a bodyweight coefficient.
Worked example from the stored table
The site’s current table contains a multiplier of 1.130 at age 50. With a 600 kg total, the displayed adjusted total is 600 × 1.130 = 678.0 kg. This is a mathematical adjusted quantity; it does not mean the lifter physically lifted 678 kg.
If an event instead applied that multiplier to a bodyweight-adjusted score of 400 points, the result would be 452 points. Those two results have different units and meanings. A calculator must say which calculation it performed.
Age limits and rounding
The carried-over module has Foster-labelled junior entries for ages 14–23, a multiplier of 1.0 for ages 24–39, and McCulloch-labelled entries for ages 40–90. Enter a whole-number age within 14–90. The revised input validation does not silently substitute the nearest supported age for an out-of-range entry.
Which age applies at a meet?
The correct age can depend on how an organisation defines its age groups and eligibility. Do not assume that age on the day, age at year-end and the age shown in a result database are always interchangeable. Use the definition in the event’s rules.
Important limitation of the current tables
The coefficients were already present in this website’s calculator. Their original source edition has not yet been established during this rebuild. This guide documents the implementation so that the displayed output can be understood, but it does not certify the table for official scoring. An organiser’s applicable table and calculation sequence take precedence.
A useful record includes the method
For an age-adjusted comparison, save age, bodyweight, total, the base scoring formula if any, the age table edition and the final rounding convention. A result called only “age-adjusted score” leaves too much unspecified. Compare results only after checking that those choices match.
