After completing a workout only two weeks after my last FTP detection, the system prompted me to detect my FTP. I knew this was intended behavior is the system thinks that you might have a big change in FTP. The thing is, the result was only 1 watt higher than the previous detection two weeks prior and less than 2% above where I have my FTP set. Now I love an extra FTP detection, and I did happen to set some recent power PRs in the workout, but I’m wondering if this is intended behavior? Did TR reduce the minimum interval between detections?

Aha; thanks for that! It was a ~ WL 10 SS workout, so that would explain it.

Also, it sounds like it’s not a real AI FTP detection?
of course its not a “real” detection as you might think of it. but the important thing is to keep the progressive overload going and once you reached the end of “workout lvl” the logical way to adjust your intensity to your obvioiusly grown fitness is to lift your ftp marginally. the same goes for the other way around.

No, it sounds like it was “real”. It was triggered by the workout level, but your FTP hasn’t actually change much. The “adjustment” would have raised your FTP by 2%.
The annoying part of this is that the arbitrary 2% bump in FTP pushed my next available detection four weeks out from the later date. By the time that rolls around, it will be over six weeks since I was able to have the AI model detect my FTP.
FTP Adjustments shouldn’t affect the 28-day timer linked to an FTP detection.
When was the last time you ran AI FTP Detection and accepted the results?
I last detected my FTP exactly four weeks ago on 11/11 (I normally do not ‘accept’ because I only change my FTP in 10W increments to maintain PL continuity).
I completed a high PL SS workout on 11/27 and was prompted to “Detect My FTP,” which I clicked thinking it would run my history through the model and it gave a number 2% higher than my current setting. My understanding now is that this is just an arbitrary 2% recommended bump. I did not accept. Now my next detection date has been pushed out to 12/25.

By that do you mean that if you have successfully completed a PL 10 workout, you would rather next do a PL 10.5 workout at an FTP setting that is lower than the one TR calculates as being correct for you, than do a PL 9.5 at that higher, calculated, FTP?
The WL 6.8 threshold workout that I recently completed was slightly more difficult than the WL 9.8 ss ride I completed. I like to bump my FTP 10W when I get into the mid 7s on threshold or the mid 8s on V02. I’m not quite there yet.
I think TR is making a mistake by including SS in the arbitrary 2% bump at level 9+. After 1,300 TR workouts, I have discovered that although the relationship between SS and threshold WLs varies a bit with duration and interval length, in no case is a level 9 ss anywhere near as difficult as a level 9 threshold.
You can turn AIFTP off.
By doing that it would no longer interfere with your own method of determining when to bump your FTP 10W.
What works for you, that is all that matters. 1,300 workouts is a good tally and your recent PRs show that it is working for you.
That said, I am a bit confused by the somewhat different positions you take in this thread. First writing that you love an extra FTP detection, then that it annoyed you that your next FTP detection was delayed and later writing that you ignore the results of FTP detections anyway, in favour of your own system of FTP management. If you are going to ignore it, what does it matter when it happens, or what it says?
I agree that SS shouldn’t be included in the 2% bump - anyone with a correctly set FTP (so correct even Coggan would agree with it) could do a level 9 SS workout - which would then by definition lead to an FTP setting 2% high 
Also, and I know I sould like a broken record on this, but I’m really intrigued as to how people - definitely not just the OP - have ended up doing these high level SS workouts?
SS workouts should feel like 7/10 difficulty; but as the OP has stated, trainerroad has got them doing SS workouts that are around the same difficulty as the threshold workouts they are being prescribed.
I can’t say I’ve ever noticed adaptive training trying to push my SS workouts too high.
This did make me chuckle - sounds like you have your own solution - and it is working for you.
Must admit I have noticed a similar pattern - when i’m at the point of a plan and my threshold PL level is above 5.5 then I’d expect AI FTP to signal an increase in FTP.
In my opinion your method is waiting for a too high PL level (i’d go for 6 instead of 7) and the 10w jump is a little too wide (I’d go for 5w). This is just my opinion though - if what you are doing is working for you then stick with it. I think this is why AI FTP is trying to push your FTP higher than you think it should be.
