Whats the general consensus on the effectiveness of Zwifts Build Me Up plan when used with a power meter versus relying on virtual power alone? Does the investment in a power meter significantly enhance the accuracy and overall training experience, or can users still reap substantial benefits without one? Considering the added cost of a power meter and potential hardware compatibility issues, is the incremental gain worth the investment for those with limited budgets or who prioritize other aspects of their training setup?
Are there any notable differences in the types of workouts and training phases where a power meter provides the most value, or is it more about the consistency and precision of the data it provides throughout the entire Build Me Up program? For those who have used the plan with both power meters and virtual power, how would you rate the comparative effectiveness of each approach in terms of achieving training goals and tangible performance gains?
Moreover, what are the implications of using the Build Me Up plan with a high degree of variability in power output, such as when using a smart trainer with known power dropouts or opting for a more affordable non-smart trainer with a power meter? Can users still trust the predictive capabilities of the plan and the estimated FTP values it provides, or does the added uncertainty compromise the overall validity and reliability of the training data?
