I never really paid attention. But so far I have recieved about 600 unique hits today, and based on past information I get a health amount of click throughs. But for all dang day since 12am, no stat changes or anything. Do they only update daily? AND YES DANGIT I DID A TYPO IN THE TITLE OF THIS POST!!
Stats are supposed to be real-time but often the server gets bogged down and there can be a delay of several hours before reports update.
I've often waited a number of hours for stats to update as well (usually 2-4). I can't remember a single time when I have had stats that were up to the minute from CJ.
