I'd like to add that while David's post gives what may be the best guide available anywhere on the use of technology to improve the quality of your swimming, your practice and your ability to analyze objectively, we have also corresponded on the degree to which we both value using simple human memory to track nearly every key detail from my practice.
Virtually all the practices I've logged -- mostly on the Favorite Sets and Practices conference -- have been done without a data-tracking device like SwimSense. Through years of practice I've developed the ability to recall nearly every repeat - distance, time, stroke count, and tempo -- during an hour of practice, to be logged later after I get home. I'm confident this adds to the brain optimization created by mindful practice in the pool.
Still, I've got a new SwimSense and am looking forward to using it because the Finis web site has some cool graphing and data analysis capabilities.
