Training readiness after two days of workouts

Should it not be:  40 plus 40 minus time between workouts?

Not really. It is more complex, and factors like the intensity of the last workout, training effect, stress, sleep , daily activity levels, etc. play a role. Read more details on it here:

In totally understand that there a more factors which this depends on, but don't you agree that saying 'you started a new training, so your previous recovery time doesn't excist anymore?' also isn't right?

Than it should be more like:

40 minus 'recovery between training' plus new recovery time?

I will read the articles you applied, thank you for that.

No, I don't. You might have recovered faster than expected. And then the Training Readiness is telling how much time you need for the recovery if you want to repeat a workout of similar intensity. So if the intensities of individual workouts differ, then the estimate will differ too.

From previously the linked article:

This metric provides a recommendation for the amount of time you should rest before doing another workout of the same intensity.
