my comments on length of time spent practicing
5 minutes of bad practice is too much and counter productive in most cases which is why I said,
"No you can't practice too much unless you are practicing wrong"
When you get to the level you ("you" meaning Gummerson) are at, the amount of time becomes less important because you can put in less time and maintain and you can put in smart time and learn things much faster.
However, if someone were to compare you to a person just starting out and lets assume you are both going to learn something new – the same something. I expect your learning curve to be much shorter because you have a lot of previous learning to draw on. You have muscle memory, tournament wisdom, practice experience, etc to draw on which helps you learn.
I don’t care how smart a person’s practice is, if they only practiced as often as you do now (what, less than 5 hours a week right, I contend they will never reach top PM level. I don’t think it is possible.
A person will make the best of his practice to do things like you mention in your post but, without quantity at some time in their development, they will, I propose, never get to the top level - this is why Todd Loffredo said, "20 hours a week when I was younger for a few years.. There needs to be a time when you eat and drink and sleep foosball in order to master the game I believe.. At least for me.. "
more time isn't better if the time is bad time but more time which is good, is always better than less time
