4DP test without heart rate data
I have found that when I connect my heart rate sensor to the sufferfest app, the HR data is inaccurate. It gives me a HR lower than what it actually is (when compared to my watch and manually checking HR). For this reason, I did not connect my HR sensor to the app during the 4DP test. The results say "We're not fully confident in this result because: You didn't have heart rate data for this activity. No LTHR will be calculated". Does this really matter? I have a really good idea of what my LTHR is so I manually entered it. Will this somehow effect my power targets or does it only matter for HR zones?
