Remember the things I forget

I did drills tonight. Simple drills like straight drive to myself and taking it off the back wall also. I also did boast to a drop, cross, lob, and drive. Lastly I practiced a two wall boast. Three wall boast are the most common among club players, but I'm finding a very soft two wall boast that bisects the front wall dies really nicely in the front. The noteworthy thing happened after 45 minutes of practice. I began using a windup motion to time my swing. The windup on the forehand involves putting my hand out in front of me along the trajectory of the ball and rotating my left shoulder forward. On the backhand side the windup is similar. I start by making sure my racquet face is up and open. Then I rotate my right shoulder forward while bringing in my elbow. I finish the swing by stepping forward with my right foot. This rather complex bit of swing came back to me without my thinking about it, but it did take a long time on the court before they revealed themselves. My goal is to be able to start a practice or match with this proper technique during the warmup.
