No, I am not stupid. I tried to do that math but it doesn't work. I know after experimenting that it isn't just # of cancelled rides divided by # of trips accepted.
(# of driver-initiated cancelled rides) / (# of rides accepted) = ??? Nope.
I asked Uber. Guess what. They never wrote back. LOL.
That math seems to be correct. However, are you looking at the right window?
The driver's cancellation rate is indeed the number of trips you, as a driver, have cancelled divided by the number of ride requests you have accepted. Your math seems to be correct.
However, this is a rolling calculation of the last 7 days. The equation ignores all figures (both cancellations and trips accepted) from 8 days ago or more. Try doing the math again with only the recent dates.
- When a rider cancels a trip, it is not counted towards your cancellation number. Hence it does not increase your cancellation rate, but it will help you reduce it because the denominator, # of rides accepted, goes up.
- It is known that when drivers take a few days off (i.e. stay offline), the cancellation rate spikes higher. This is due to the fact that you still have cancellations from when you were driving, but you are not accepting any new trips. If you are not accepting any trips, your denominator decreases, even though you are still carrying the cancellation number from when you were driving.
