It's a bit off-topic, but have you noticed that model listing on your profile page are erratic too? On my page they aren't sorted by upload date, nor category, nor alphabetically, nor view counts, nor price. What's left to sort by that I apparently haven't figured out? The general rating system, perhaps?
Response rate and average response time also don't seem to be relative. I have a response rate of 86% with an average response time of 0.9 h, whereas another designer has a response rate of 89% with response time of 5,9 h. The description says, "Support quality shows how well and swiftly the user responds to messages." I don't see how swiftness factors into the results when taking 5 hours longer to get back to someone yields a 3% higher response rate. Maybe the 'wellness' factor needs a bit more transparency. And besides that, customer and general user contact is all lumped together, so it's not really a reflection of 'speedy customer service'.
It's all kind of 'Alice in Wonderland'-ish, so I'm going to let it slide. I just wanted to point out the other places the 'magic factor' seems to be influencing ranks and ratings.
