How do you determine the supercompensation period for your muscles and body after exercise?

Supercompensation is the post training period during which the trained function/parameter has a higher performance capacity than it did prior to the training period.

But how do you determine when the supercompensation period begins? Is there an average that people can rely on?

Should it be 1 day after exercising? 2 days after? Is it different for different muscle groups? Is it significantly different for different people?

Example: Let’s say you do as many pushups as you possibly can in a normal pushup session. When would your supercompensation point begin?
