@raven I appreciate how confidently you can say what I didn’t do. If you look at my graph you will see 40 minutes of steady pace / effort. I am not even skeptical about the AeT value reported - that would still have little value to ny training - but rather about the fact that ZS shows I’m still doing aerobic training when my effort increases (also shown in the graph).
Right, that steady pace at the start looks to be around 5:50/km and you reported you go above your aerobic threshold these days at 6:00/km
Quoting you: “ My aerobic runs used to be around 5:30 min/km below 145 bpm, now I’m well above that heart rate at 6:00 min/km. Today after 40 minutes of another miserably slow run with elevated HR”
Given your own reporting, that chart and info didn’t look like an easy warm up effort to me but instead an effort over threshold. ZoneSense requires a lighter effort in the first ten minutes. However, I admit may have read the chart wrong though or misunderstood you.
If aerobic threshold (AeT) = 162 bpm, and Anaerobic threshold (AnT) typically sits 10–20 bpm higher than AeT, then an estimate of that would be: 172–182 bpm. Then max HR is higher than that. If all if that sounds right, then perhaps ZoneSense is correct.
However, note an effort below AeT typically should pass a “talk test,” being able to speak whole sentences comfortably, without gasping for breath.
