I don't know, some of these numbers are a little misleading. I know you're using the lowest sales after fees, but there's no way problem free examples can be bought for these prices. Take for example the 2011-s unc or 2013-w enhanced, both in spot free graded 70, which is all I buy. The 2011-s sells in the $300 range, not $100 and the 2013 sells in the $100 range, not $50. I've been buying a few EU70 2013-w's and contacting sellers to determine condition. I'm finding even in the $100 range, 90% of them have spots. So, it looks like sellers on eBay are mostly willing to sell only problem coins in this depressed market. Now that many of these coins have been out for awhile, maybe a better way to look at the values is, what would you have to pay for problem free examples.
