Thanks @nicoguilbert @thekappe @Marjaana @amn2099 youâre touching very important points.
âHaving recurring tests will ensure that your zones are kept aligned with your fitness status.â
This is so true and, as Marjaana says, not every athlete greets test day with equal enthusiasm 
As maximum efforts done during tests are slipping away from the 6-month window used to build the profile, our thresholds might change. If racing is not that frequent that max efforts are repeated on a regular basis (for the majority of the athletes) then, as you all noticed building a reliable profile becomes problematic.
We are exploring the possibility to include tests in the Workout Wizard and prompt the athlete to take a test when we notice a unrealistic change in the thresholds. It will most likely be included for a key session of the week, where the body has to be perfectly tuned for a test.
RE thresholds. Athletica currently relies on CP for the Z3-Z4 separation, MAP for the Z5-Z6 separation, and MPP for the Z6-Z7 determination. However, if you pre-select your own CP, all the zones are taken as % of that threshold.
MAP, which is guiding the boundary between Z5 and 6 is heavily influenced by max efforts <5â, and very much by a 5â maximum average. The best you can do if you find that your 30":30" are prescribed too low, is to take a 5â all-out time trial test instead of doing a 30":30" session. Now, we are perfectly aware of the fact that this should be prescribed by the AI-coach. To the same extent, MPP is guided by 5-10" efforts, and CP is influenced by max efforts within <1h. So a way to influence CP is to do max efforts at 3â, 12â, 20â, etc. Ideally, these can be gathered by the application of what we call âinvisible monitoringâ, given that, from time to time, athletes naturally push themselves to the limits on those time ranges.
Again, we so much agree with what you reported, and we look forward to implement âtestâ sessions in the WW.
