Depends what you are looking at - if it's your 365 day rating then it's averaged not over 365 days but over the last 500 (I think?) trips. So once you build up to that amount of trips, the average will rarely deviate.4.85
Not really sure how it is calculated. Initially I thought it was a 2 week moving average. But lately no matter. How many 5 I get. It doesn't seem to change.
When I first started with Uber, it was possible to look at your ratings (using the partners.uber.com portal) to watch your overall and daily rating from trip to trip. Uber has gone to great lengths to make sure you can't do this now. Don't try to work out who may or may not have rated you badly - they disguise it all. There is a very good reason for this, and that is that if you work out what arsehole rated 1* because you didn't give them a 40c bottle of water for their $6 min fare or you were't driving a 100k BMW then you aren't going to pick them up again if you recognise their name/ph number when you get a request from them again.I do realize that and you could be right but after just that rider (it was my last pax for the night and just after midnight) my daily stats were showing as 0 where normally no ratings have always appeared as - . Immediately after restarting the app the last trip total was showing as n/a and i also got an email from uber saying that a problem with the system had caused problems with some fares and they would be fixing it. It's not unreasonable to assume that possibly the passengers app also crashed or when they fixed the problem the rating field was messed up.
After driving again in the afternoon, my final daily rating was 4.5 for 16 trips. For me to be on 4.5 i would need to have half of the pax give me 4 stars, which is possible but hasn't happened to me before.
At the time i calculated that ratings of 1x0* 3x4* 12x5* would = 4.5*
Also, i'm not completely sure, but i think my overall rating after that trip dropped from 4.9 to 4.73 before settling on 4.77 by the end of the day.
