Great to have you with us, Ulrich!
When you do find time to get out to practice, I've found that it's better for me when I am able to work in several shorter sessions of like 20-30 minutes and focus on one thing (straight line path, accuracy at 30', whatever) rather than setting aside an hour or seventy-five minutes. As Joey and I were discussing yesterday, I get tired and then I start reinforcing bad habits and locking them into my "muscle memory" which I then have to unlearn.
YMMV, and I get that we all have other things sucking up our time if you can't get out to the yard a couple or three times a week.
