For cumulative goals, show the actual avg weekly rate, and not just the goal rate
I'm measuring how many hours of sleep I get, and I have set a goal rate of 53/week. I'd like to increase my target rate since I am always above the road. But since I can't see how many hours of sleep I am currently getting in a week, it's harder to calibrate my goal rate to an ambitious but realistic level.
Showing actual rates would allow users to compare their performance with their goal more easily.

I agree this would be nice to have! Right now I am doing all this math by hand.

Let's say I want to commit to sleep a 6 hours per day. It should NOT work if I sleep 3 hours in a day, 2 hours in another and compensate in the rest.
