Thanks. That is helpful. I have busy work weeks for sure. My riding tends to be one ride indoors mid week and two outdoors Saturday and Sunday. If I have more time midweek I tend to do short zwift races. Once the colder weather kicks in il usually transition to mostly indoor riding. It sounds like I should stay clear of AT till then? It’s interesting you say that because another post said that the machine learning still applies to outdoor rides but considers that you completed them successfully. It does still ask for feedback about how I felt and I don’t see why they can’t use heart rate and that feedback to make some basic recommendations?
