I did an ad hoc FTP test today and have a bunch of questions after my results. Old La Honda is my closest benchmark climb and my previous PR was 21+mins, but I never went “Full Gas” on the way up. Today I went full gas, and had a material uplift in my Training Peaks threshold, from 295 to 311 (plus a goal & PR) .

First, how should I think about heart rate? I am 46 years old, and my HR was between 160-166, but averaged 162bpm on the segment. This felt like full gas, but is that indicative of a lesser effort? I was surprised it was that low given how hard it felt (I think 173 or 174 is my max HR).
Second, this is a big uplift in FTP, but I hadn’t done a proper test before. Is doing this on a hill with a ~8% average grade representative (the suggestion was a 2-3% grade in the article)? I had a cadence ranging between 90 seated and high 70s when standing, but there were definite power spikes when it was steeper. Before I try to do SST off this number, I thought it would be good to make sure I am not overdoing it.
Lastly, how much does fatigue impact the accuracy of the result. I came into today feeling pretty beat (I believe the TP form was -41, fatigue was 149. I had not planned to go full gas today, but I felt good when I got the hill and decided to take a shot.
