What are some unconventional ways to use Zwifts data to identify strengths and weaknesses, beyond the usual metrics of watts per kilogram and FTP, that could help riders gain a more nuanced understanding of their performance and pinpoint areas for improvement? For example, are there any novel applications of Zwifts data that could be used to analyze a riders pedaling technique, or identify inefficiencies in their gear shifting and cadence? Are there any creative ways to use Zwifts data to develop targeted training plans that focus on addressing specific weaknesses, rather than just blindly chasing watts? How can riders use Zwifts data to identify their optimal pace and power output for different types of rides and terrain, and what are some strategies for using this data to inform their training and racing decisions?
