Optimal Practice Frequency?

I know 20-30min practice sessions are good for growth, but how many sessions a day is best? For example, 5 sessions a day with 2h breaks in between or 2 sessions a day with a 10 hour break in between. What would be the optimal time between practice sessions for the fastest improvement. This is assuming I have all day, and I dont mind spending hours a day aim training even if it's a bit excessive (as long as its not counterproductive of course). For reference, I play Valorant.
