Randy and Scott have put it all out there for anyone who wants to apply it. The only thing I would add is that between the focused practice sessions, and the actual playing (league, tournaments, etc) there is also what Randy refers to as "sparring". Sparring is what we do to simulate serious competition while still learning. Whenever we get together to teach a class, we usually find time the night before the class for an instructors ring game. It's a chance to test ourselves in a game setting, attempt shots we might not normally try in a serious match, and just enjoy playing for playing's sake. It's not what we call practice, nor is it serious competition. If I am getting ready for a competitive match, I enjoy finding a sparring partner before my match gets called. It's much better than trying to do any serious practice at that point. I try never to "practice" on game day.
