Specificity Rating

This is a percentage value that provides further detail on a Focus. With Focus Duration characterizing the duration along the Power Duration curve being focused on, Specificity Rating characterizes how specific the strain accumulated matches the precise work allocation ratios. 100% specificity rating is Pure and means that all the strain accumulated was at the power on the Power Duration chart associated with the Focus Duration. 0% specificity rating is Polar and all the strain accumulated was either at Peak Power or below Threshold Power. Generally speaking, cycling often has specificity ratings that are in-between pure and polar. These are classified as Mixed.

  • Pure = 100% – 67%
  • Mixed = 67% – 33%
  • Polar = 33% – 0%

Ultra-Short Race Pace Training (USRPT), for instance, is an example of training at a pure specificity rating. Training is done at intensities that match a given intensity only.
