Hi,

It takes several hours for changes you make to be propagated to all G's ad servers, so changes you make will not go into place immediately.

There can also be time delays in the stats coming through.

I believe you may need to look at least 2 days either sid of a change to make sure you have eleiminated all the timining issues.

I'd also recommend not drawing too many conclusions from any day-to-day comparisons - the effects of different days of the week can swamp them.
