I have the same for the week, but wasn't chasing it, got only two ORD trips from today. So for the weekend they sent me 18 for $35. To make it up for this sucky incentive Uber added Friday afternoon quest 8 for $40 or 5 for $20 from 4pm to 6pm...in best case scenario I could make up to $75 weekend promotion for 18 trips. But 8 trips in 3 hours is quite a challenge during the rush hour.18 for $25. I guess this is my punishment for doing the 15 for $55 quest this week.
