Here are few different interpretations.
We have looked at some different types of testing.
The most important thing to note is do we have increasing smo2 during steady work ?
or do we have stable smo2 during steady work ?
or do we have declining smo2 during steady work ?
These are usually very easy ways to find Aerobic Threshold, Tempo, Threshold during a step test.
Below are 3 examples of a similar workout of the same athlete during a ten day period starting a long tempo interval block.
This was the first workout of the session, based on heart rate, power and power to heart rate I would say this was just fine.
If we look at the smo2, it would have been better to do the first interval a little lower, to have a more stable smo2, and then the second interval would have likely been a higher wattage, but both with the same perceived exertion.

Below is the second session
Similar but shows the same pictureā¦

The third session
Another similar picture.
So the moral here is that I feel if you have a goal wattage, the first interval should always be a little easier than that goal.
The second interval should be likely on that goal.
The third if there is one could likely be above that goal. Creating a building wattage session.
Now, if you were to use the moxy live, which the athlete will do next week, they will make sure NOT to let the smo2 decline on the second interval, getting as close to the wattage goal as possible.
Then second interval goal will be to do the same, but wattage will likely be higher.
For the third same idea, and again the wattage will likely be higher.
So all those times you wondered why the more intervals you do the better they feltā¦this is why.
So using a moxy can help through defining training zones in testing, but better yet it really helps make sure you do the right load within a range to help make every workout at the right level.
