Click count displaying negative count

[Brad Turner [ILM MVP]]

On my feed (feeds.feedburner.com/idchaos) I am attempting to track
clicks on a particular link. If I go through Outgoing Site Traffic,
set the summary stats for the last 30 days and select the link I'm
after I see the following results:

clicks on this link (no number displayed)
74 views of this link
16.2% click-through rate

Pages Containing this link display the click counts correctly, however
at the bottom I see this:

... plus -12 other clicks on this link.

If I add the clicks in the Pages table I get 12. So the "clicks on
this link" is not tallying correctly and the bottom summary is somehow
displaying the correct number although a negative one.

The other strange think is that I have this and one other link in the
same post - they don't appear anywhere else in any other posting, yet
the View counts are different. If I understand correctly, the View
count should include how many times the page containing the link was
displayed but if that were true, you should not be able to see/display/
impress one link without the other.

Does the View count somehow count readers auto-downloading attachments
and the readers are downloading the PDF and not the ZIP link?

Thanks,
Brad Turner
