It would be really cool to have the functionality to break down the workout into sets. i.e. a swim workout that had 500 yrds warmup, 10 x 100 on the 1:30 … and have it add it up for you in terms of total time and distance also down the road you could de reports on certain sets to see how you have improved. This would not only be good for swimming, but also intervals in running and biking. It’s just one more way to break down a workout into it’s parts in a meaningful way.
