Using Heart Rate and Power for better training analysis

Quality is like 100x better and so much more enjoyable to watch

Sup dude, you might be interested in EnDuRa from Stephen Seiler. Got some tastier intra-activity metrics and data analysis tools that delve deeper into these efficiency concepts! UI and integration isn't as nice as training peaks but handy for a deeper look 👍🏼👍🏼

Effeciency Factor, should be relative to cadence. 2 different rpm can put out 250 watts, and one will have a higher HR. So you need to compare 2 rides with similar avg. RPM, no?
