Ask HN: How to correct incorrect reporting from traffic counters?

I imagine a lot of lurkers (myself included) tend to use compete, quantcast & alexa for tracking other sites. When it comes to your personal site not being reporting correctly, have you ever tried to correct any holes in their data? We're offering to send them private info on our growth at http://gorankem.com , but compete says they have their own methodology for computing (??)

I'd hate to hear that prospective investors or the like are going off of those charts when their samples are often not fully accurate.

Anybody had issues in the past? Gotten them resolved?
