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?

    Hi Whitney,


    This will only affect HR zones.  Power targets should be just fine.
