Tom, I listened to Terry on this link and tried to implement it when I got back in the pool. As I said previously, my SPL had increased lately as I tried to imitate Terry's timing in his TI demo, and I couldn't understand why. By paying attention to two different things he pointed out in the above thread, I got my SPL back down again. First, start the catch by using the muscles on the top of your shoulder to raise your shoulder as the hand drops, second, to concentrate on holding the ball of water you catch as your arm moves back in the stroke. When I first started doing this, my SPL dropped, but I was surprised that it seemed to require some strength and effort. Over time, I noticed that by coordinating my recovery and rotation on the other side with the motion of the ball, the effort went down considerably. So that was just one session. My times were normal for me, but my SPL dropped by 2-3. We'll see how easy it is to hold onto and improve on this change.
