I found that you are exactly correct - it is very easy to practice bad habits without realizing it. A coach/observer can make very helpful comments with some basic training as to what the maneuvers should look like. I have been fortunate these past two years in that my wife enjoys the SPA camaraderie and, yes, there are a lot of wives who come to the contests. Linda has turned into a great caller and she can make good and helpful observations about my flying. It helps.
