Primary language: C#
Description: This project allows Zwift users to monitor their moving average power and FTP in real-time.  It also provides valuable metrics to the rider such as average and normalized power (NP), intensity factor (IF), and training stress score (TSS).  For the racer and time-trialist, there's also the ability to configure distance based splits with optional goals.
