In cycling there are three main factors that go into "skill". Speed, cadence, and power. We measure speed with MPH and KmPH. We measure cadence by counting how many times the crank arms turn. We measure power in a silly way, which is expensive. I Think the only way is to have one of those power reading hubs.

Anyway, yes, and yes. But don't pay attention to that stuff. Just look at your speed if you want to do better.
