Ok so Google as always has the answers, like I said in my first post. I looked at a few studies and sights. You can Google it yourself like I did.
"Optimal practice time to learn a skill"
The takeaway I got was...
Even for top world class performers across many topics,
Mindful "deliberate practice" was the key. Mindless practice was counter productive as it in grains bad habits. Mindful practice of one hour sessions totaling no more than 4 hours a day is best. The greatest benifits were gained in the first 20 minutes and would decline the longer practice was done.
Here is a thing. Mindfull practice takes conditioning. One of the reasons I do fitness. So I am not that guy standing in the corner getting his breath back.
Sparring is evident of that. If I do ten rounds I will be better than if I do two.
