On the dashboard I would like to see something similar to the "Time in heart rate zones" chart but as a pie chart showing % of time spent in each zone over the selected time. This would look something like the "Fitness summary" chart but for heart rate. The same thing for "Time in power zone" or "Time in speed zone" would also be very useful. Basically, a way to see if I am in sticking to 80/20 at a glance.
