no they’re not, i’ve done lots of TR workouts pushed to my gamin and did progression levels. but i’m assuming you’re talking about unstructured workouts, i’d bet more often than not that people aren’t fitting in that much work that it would register highly on a progression level scale. even doing like 45mins of sweet spot in a long ride would be like a 3.9 on progression levels
honestly I think a lot of people are putting way too much stock in unstructured outside rides as far as their impact on progression levels
