Matthias,
The swim analysis should provide you with the same features as the bike and run. For example, see one of my athletes recent SMI1 workout, a complex workout. You can see that the athlete first followed the structure of the workout. The peaks and valleys of the actual (green lines) follow the planned (blue graph).

Additionally, the distribution of intensity matches the description. The SMI1 is 1750 yards, with 500 in Zone 3 and 250 in Zone 4. You can see that the athlete spent 26 minutes at Zone 1 Zone 2 (the first 4 bars), and 12 minutes at Zone 3 or higher. A practically perfect execution.

If you don’t see these charts when you click on Analyze, it may be that your device is not tracking pace.
