If what they say is the case, then what happens when i complete a recovery workout such as Obelisk (endurance 1.0) whilst my Endurance PL is 5.5. Would my PL then take a hit??? That comment from TR support just has to be incorrect.
Sounds wrong to me and more like this bug mentioned above: 🎉 🎉 🎉 Introducing Adaptive Training! 🎉 🎉 🎉 - #3957 by PotsieA
I’ve never seen a lower level workout rated moderate decrease my PLs.
A bit more detail of the problem for those who strike something similar and wonder what is going on.
I completed Starr King Productive Threshold yesterday and it showed as Productive on the Past Rides page and a -1.9 PL adjustment.
I then did Antelope Productive SS today and it also showed as Productive on the Past Rides page and a -1.4 PL adjustment.
The good news is that despite the apparent negative PL adjustments, the PL’s on the Career page were adjusted upwards correctly.
The treatment within the workout detail was a bit off too.
Starr King Threshold only had a Primary Progression for Endurance and showed as Stretch , and Antelope SS only had a Primary Progression for Tempo and also showed as Stretch
All a bit weird, but the team are on to it.
Have done.
Something I noticed afterwards and is similar to that problem reported by @IceBear - prior to the workout my threshold PL was 5.2, Ritter has a difficulty rating of “Threshold 4.4” so the “reduction” I saw was AT matching the workout difficulty rather than a failure as such. However …
If I go to my career page (actually “went” as something has changed overnight) then my Threshold PL is still 5.2. That was last night. I looked at my career page a moment ago and my Threshold PL is 6.2 and the workout is marked as “Achievable -1.8” i.e. there’s a difference of 1.0 between the values I saw yesterday evening and those today. That’s similar to what @PWeber is describing.
I’ll update my ticket with the above info.
Support have confirmed it is a bug; I’ve also confirmed the reduction is only showing on the workout. On my career page my actual progression levels have not been reduced. (Same as several reports above)
Sure sounds like a bug and I get that TR will likely fix it quickly.
Aside from that, I’m not thrilled to hear about another questionable response from support. The comments from support are nonsense and another example of bad and misleading info from support.
This follows the Pass survey responses from support (multiple occasions and reps apparently) that were giving questionable and contradictory information.
It raises serious doubt in my mind about what we can or cannot trust since there seems to be some communication issues between TR proper and support agents. I suggest that TR review these mistakes and do what is needed to correct the problem.
I have real respect for TR support based on my past experiences, but these recent issues are not great examples and need to be improved.
yeah, that’s a pretty poor response. Sounds like training is needed as this agent clearly misunderstands how it works.
Don’t know if this has been answered already…almost 4000 posts are hard to go through 
How does AT know with the surveys if a person is just a whiner (lets say passing workouts but always saying it was too hard) or at the other end of the spectrum, somebody who says everything is easy but just barely passes the workouts?
How does one “calibrate” perceived exertion to guide the AI correctly? For example: a good sweetspot workout should be hard or moderate or very hard?
By the way I also got negative progression on a passed workout too.
Hopefully the machine learning learns this. So if AT thinks a workout should be “3. Hard” and someone rates it “1. Easy” and does so consistently then it should be adjusting the input accordingly.
There’s a post from @IvyAudrain either in this thread or the Easy vs Moderate vs Hard thread about what each level should indicate.
I think that’s exactly why the initial guidance was just to rate each workout according to your own perception on the scale.
Obviously it’s got a lot murkier since.
It really sounds like TR doesn’t have an internal FAQ / knowledge base for its support team on AT. So there isn’t a common understanding for how AT should work.
I work for a SaaS company, and with every release / introduction of a new product, our product managers do TOIs (transfer of information) & KBs for our support team, so support understands new product / features and correctly and consistently can respond to customer questions / issues.
Something is clearly off for them to not be on that same page. Maybe they didn’t read their TPS reports 
Hmm, just did Tunnabora - Log In to TrainerRoad, should have been tomorrow but decided to do it now. Got the “pass” survey, gave “Easy” as the answer, well because it was. Was spot on with the power figures and was pretty consistent - that road was resurfaced recently and there’s a “join” at the top - I was within two bike lengths of that on each interval.
The Calendar shows -1.7 for Sweet Spot PL but there’s nothing on the workout page linked to.
Support said that new progression logic and new post-workout survey were recently deployed. And support manually set my Wed workout to moderate.
And interestingly I now have progression levels waking up:
and Echo -3 from June 11th is now showing PL updates:
along with PL updates for January/February custom outside workouts (from TP):
No workout scoring starting March 1st as I disabled TP-to-TR workout sync on Feb 27th. Re-enabled on April 27th and workout scores reappear but no PL for custom workouts except those in Jan/Feb. So I suspect that generic outside workout support is getting closer.
This is also a self correcting system to a certain extent. If you say a hard workout is “too easy,” and AT progresses you to the next workout, the chances are higher you will struggle or fail. Once you struggle or fail, it will lower your progression hopefully to where it should be.
If you are sandbagging and saying easy workouts are “too hard” then obviously your progression will stop or go backwards and you only be hurting yourself. Hopefully in your boredom or the easiness of the workouts, you’ll change the way you respond to get the progression going again.
I can confirm, when viewing the ride analysis page, you may see a false decrease in Progression Levels if you completed a ride below your current level. To clarify, completing a ride below your progression level should not actually drop your progression levels.
Those false decreases can be seen on the ride analysis page, but are also displaying on workout cards on the Career and Calendar pages, not just on the Past Ride Details page.
This false decrease display won’t actually change your Progression Levels, and you should still see accurate PLs on your Career page.
We definitely agree, and recognize that misinformation was given out in this scenario. Our team is documenting items daily to educate everyone internally, support team included, on the nuances of Adapting Training, bugs, how to speak to them, and better create consistent messaging for each AT item.
This current report has now been distributed to the team, and feedback like this gives us great examples of where we can continue to improve.
The false Progression Level drops occur on workouts above your current PL also.
Fixing that bug should fix those false progression displays of all kinds. Until then: your Career Page is the best, most accurate place to view your Progression Levels. 
Thanks @IvyAudrain. I’ll log this with support also, but it appears there are now lots of negatives showing on the calendar:
This is happening in both the web-client and also on my Mac.
