In Navy flight training you are taught to do a continuous turn on the crosswind to downwind leg, and then also when you make your turn off the downwind it is one continuous turn to final. You will of course have to make adjustments for an overshooting or undershooting crosswind, but after a few trips in the pattern you should have it figured out. The main advantage of this technique is that it allows you to fly a tighter pattern, and when you are doing 20 to 30 T&G's flying a tighter pattern will get you more passes in the pattern when you have only a set amount of time to do pattern work.
