I’m sure this question has been asked before but I couldn’t find it.
I get that xss is primarily a power function I just wonder if it ever takes into account the exertion of a ride as evidenced by heart rate. Example, heart rate was about 10 points elevated on average probably due to heat and wind. I feel like I worked a lot harder than a similar ride with I’m assuming the same xss although although I have not checked. Either way, I definitely feel like it was a harder workout so wondering if that metric ever gets accounted for anywhere.
