I am trying to find a way to take the slope and intercept data from the heart rate vs. power graph and use it to create a separate metric. For example, yesterday's ride gives me a formula of HR= 0.199(Power) + 94.3, I would like to take that information and instead of using the typical150 BPM to calculate power like it does at the bottom, I want to use 135 BPM. After doing that, I want to plot this value over time in my trends tab so I can see how my power is increasing at this intensity because I typically do my endurance rides at a set HR rather than power.
Ways to create metrics of power at a specific HR has been asked and answered a few times already, but they calculate this based off of full ride averages, and the value given is significantly lower than I would expect. The values I get from the formula created on the heart rate vs power graph is exactly the values I would expect so I want to try and use those.
Thank you
