Estimated revenue lower than actual ?

[macblogger]

Hi guys, It's very strange, from yesterday I have had 6 clicks and estimated revenue was $2 and now when I look at my stats 24h later when the actual revenue is shown it's only $0.95...it has never happened to me before because it's stock market domain name and clicks always at least double and they all were from US...do you know what the problem could be ?
