I notice my stats in HTML improvements reverted to an earlier data set yesterday, one that's at least a fortnight out of date. So this may not be the only bug.
I don't check the links in that often so I can't give a percentage, but they do seem to be down on what I remember. What's left is as much junk as genuine.
