Flycast/Engage stats biased?

Hello,

We started sending some inventory to Flycast/Engage
again (after withdrawing most of it during the
extremely dry period). However, there is a huge
discrepency in reporting - one that we haven't
observed with any other agency or network. We are
using Central Ad Pro to track our stats:

Yesterday, Engage reported only 40% of the impressions
we sent them BUT their reported CTR is 4 times higher
than the one we observed. Today, Engage is reporting
only 25% of the actual impressions while their reported
CTR is 3.3 times higher than what our stats indicate.


I find this puzzling. I don't see any particular
pattern, other than that Engage underreports the
imp[ressions and overreports the clickthrough rate. It
cannot be cache, since we are busting it a) by JAVA on
our site (generating random numbers) and b) by cookies
(a Central Ad feature).

Anybody else has these problems? Any suggestions for
how to close the gap?

Thanks in advance
