RLGL is only going to approach being accurate after it has gotten a decent history of your consistent training. (Probably 6-8 weeks).
If you’re coming off a significant break or you haven’t fed your other training data into it (link your Strava), it’s going to think you’re over doing it.
On the flip side, how are you answering the post-workout surveys? If you’re saying that in those that rides felt hard that aren’t supposed to, then maybe your FTP is set too high and you really are overdoing it. Yes AT should adjust to that a bit, but if you start at PL 1 and your FTP is set too high, then I’m not sure what it will do in that situation.
