I fully agree. It is a mess and I would say there are many glitches. My response rate kept jumping strangely from 60% to 75% to 80%, qualify, not qualify... the point is, I either did not have any messages or I was sure I answered all new messages in a very short time. Also, my displayed score is 3 but one of my gigs has a rating of 4 and no other ratings... and I also got this feedback as the last one, and this particular feedback caused my score to go down to 3 (still, the gig keeps the rating of 4). I really don't know, this is the customer's second order and we are finalizing a preparation of a third custom offer... she always tips me generously and says she is very happy with my work. It is not that likely she would be leaving a terrible private review.
