correction to what I said below
I just looked at some underwater videos of people swimming freestyle and realized that what I said below is not necessarily true. That is, I claimed if I was syncing the exit of my recovery hand to the second beat, it implied that I had a hesitation in my stroke, where my recovery hand was staying at my hip. Now it occurs to me that what might really be happening is that I am slowing done the speed of my arm stroke so that my recovery can occur exactly on the second beat of the TT. Clearly I am still rather confused about what I am doing and would welcome any insights. Still, slowing down the arm stroke feels like it might be right. What impressed me was how easy the stroking seemed to be once I got in that rhythm and the reason might be because I had actually slowed down the stroking arm.
