What Is An RTT Score?

As noted above your Readiness To Train (RTT) score is a calculation based on your HRV data collected automatically by Apple Watch. We consider your 60-day baseline, the direction of the chart (which way it is sloping), smoothing and intensity values (which you can adjust), and feed them all into our algorithm to get your current value which ranges from 0 (total rest) to 10 (ready for peak performance).
