Your nav adventures sound very like mine last week when I flew from Temora to Moree, to Lismore, to Boonah, to Port Macquarie, to Maitland, to Dubbo and then Temora. I have 400 + hours and whenever I look at my chart for 3 seconds, I end up 10 degrees off heading and 200 feet + or _ in altitude. Never mind, you never stop learning and it used to be worse.
