I know it's not supposed to matter, but my first week I got all 5s. I was trying for one of their promos, and my first 10 days ended today. I think I'm supposed to keep a 4.8 rating, but it slipped to 4.78 this morning. It's been steadily downhill since last weekend. Today it fell again to 4.68. I'm pulling my hair out. I've got water, I don't make wrong turns. I try to improve the route the GPS gives me (which frequently tells me to go out of my way) I communicate with my customer to find out what they want. My car is detailed and clean. I have a power cord. Maybe I'm paranoid, but I feel like Uber has it in for me and is screwing up my rating on purpose so I can't get my guarantee. How else to explain the stellar first week and the steady precipitous drop afterward? Yesterday I drove a guy 20 miles and Uber charged him over 40 bucks. I saw 1.25x surge, but Uber insists it was 1.75x. Could it be he punished me for the excessive charge? The upshot is, the falling rating means I'm getting more 4s than 5s now and I haven't a clue why.
