OK, so I just got home from "swim practice". Apparently I only needed minor tweaking, well minor by their standards. They gave me some drills to do, and some things to focus on, and at the end of an hour I had made much improvement. Reaching a longer stroke, following through, breath control.

They suggested that I not worry about my interval times for now and just practice.

And they let me "borrow" a pair of fins....nice.
