I'm going out on a limb here. But I am assuming Randy is talking about the time it takes to ingrain a specific change. When I changed my golf swing I had to work on it specifically for 20 minutes every day for 6 weeks, at that point it would become routine. After a substantial break I could practice something else like putting but nothing that required a full swing. I could very well be wrong too. This worked great for my golf swing though.
I would really like to get some additional info on this if possible too.
BINGO. Change takes time & patience. Old habits are hard to over come!
