Corrected accuracy and pace wording in the guide explaining why aging clocks disagree.
Why aging clocks disagree no longer prints a Horvath median error figure in a discussion of precision. Instead, it explains that close agreement with calendar age across research groups does not tell a reader how close their own result will be.
The DunedinPACE discussion replaces wording about measured years of biological wear per calendar year with an estimate relative to the group used to build the clock. Worked examples now describe a pace as above or below that reference average. The guide also clarifies that the estimate can come from a single sample rather than requiring a series of personal results.
The previous phrasing could make a group statistic sound like personal accuracy and a model estimate sound like a directly measured personal speed.
Readers get narrower interpretations of the same research tools. The correction does not establish clinical benefit, personal prediction accuracy or the validity of every consumer implementation.
