My rule of thumb is that I *really* won't know what my MSN spend is on a given day until 48 to 72 hrs after that day is over. I've had to resort to guestimating my spend based on what my CPC has been historically with a campaign...and multiply that by approximate MSN page hit numbers gleaned from my own web logs.

It's not optimal. But it works. Sort of.
