Compete Stats vs. Real Stats (round 1)

Compete shows that Hacker News got 75,000 visitors in March...here:

PG stats show approx 110k + visitors:

In the past my comparisons show that compete usually only shows 70-80% of the traffic a site gets. Is anyone interested in sharing some stats on their site ( I will do the same ) to get a better picture of how inaccurate compete really is?

we get 6.5k, they show 1.75k - Probably due to the niche of my site.

- similar question - anyone want to share google traffic estimator traffic (clicks per day) vs actual clicks in top 5 organic rankings? (basically what traffic goes to ad vs organic)

-- Google says 120-240 month I get 400-700 @ avg position of 4 (40% to #1 / 25% to #2 / 20% to #3 / 15% to the rest.)

*as per AOL user data

I can't name names, but for one of sites we manage (1m+ uniques/month) compete only accounts for 79% of our traffic.

One site I am maintaining is getting like 65k a month but compete is saying ~37k a month. Totally bogus.
