2211,
I was taught the same procedure during my PPL. Everything worked out wonderfully until the day I had to fly to a busy airport and tower asked me to extend base. I can't remember how I adjusted my pattern then, but I do remember the feeling I had. I certainly didn't like it.
To learn procedures is a great thing, but only to a certain extend. It is also important to have an understanding on what happens with each procedure and each change (whether it is the flaps, the gears, the pattern or the winds).
Regards,
TG
