Looking at @IvyAudrain’s descriptions it’s apparent (well to me anyway) that there is one main scale with two or more smaller ones that overlap embedded within it depending on the workout you are doing.
For example: Pettit. Unless something is really wrong with either your stated FTP or you are ill then I wouldn’t expect anyone to respond with anything but “Easy” or perhaps “Moderate”.
Compare that with something like Leconte. Again, assuming your FTP is close to correct then you aren’t going to be choosing “Easy” and even “Moderate” is unlikely so you are left with “Hard”, “Very Hard” or “All Out”.
Simplistically the success survey is the 1-10 RPE scale divided into five slots.
AT has the expected power, actual power and (potentially) HR data all that’s really missing is your mental capacity, i.e. your power and HR data indicate that you should have struggled but you are saying it wasn’t a problem thus you can mentally cope with a workload like this.
