I just retested my Aet on treadmill it has been nearly a year from the last one. I had couple of attempts outdoors to poor results. I had done a one outdoors on the road up to our ski resort. It is a solid, sustained 10 degree slope. I jogged and ended up with a 7% delta for a starting HR of 138. After that I read not to do the test running uphill-fair enough. I am not a “runner”, although I do ~2 weekly jogs for an hour. I don’t believe that Iam strong enough runner to sustain proper HR on the terrain I have available, at the speeds necessary (hip surgery in 2019). So, I felt maybe there was some operator error.
I retested two days ago on a treadmill and got a ~1% at 138 starting HR. I pretty much new I went to low shortly into it. With the way things are (covid) and the lack of motivation to spend time on a treadmill, what can reasonably extrapolate? Aet about 140?
