Siting

Here's a blurb from a swimming website on siting:
Looking up slows you down and tires you out. If you can stay on course, you will be much better off looking up every 20 strokes as opposed to every 6 strokes. But that is a big "if." Not looking up may speed you up, but that doesn't do much good if you start swimming in circles. The classic solution to this is to practice swimming a length of the pool with your eyes closed. The lane ropes will quickly make it apparent in which direction you naturally veer. Work to straighten out your stroke.

For our purposes, let's practice popping up a bunch per length so you get a feel for the water.
