So, I got to realise that Adaptive Training does not manage all workouts: if you schedule your owns (of course) it won’t suggest adaptations for those, and it happened in the past that by moving an AT-scheduled workout to a different day of the same week, it “stopped” looking at it and never suggested necessary adaptations.
It would be nice to flag somehow the fact that a workout has been scheduled (and it’s monitored) by AT 
(selfishly, haven’t got adaptations in a little while now despite having failed a couple workouts, and I’m trying to figure out if AT is just “disconnected” or if it still considers me able to keep up with the scheduled progression…)
