Improbable adsense numbers

[SlowMove]

I'm new to adsense, and have not yet converted enough pages over to really get a good understanding of what kind of money can be made. I don't want to violate the TOS, so I won't give specific numbers.

There's no sign of a PSA anywhere when I check, the ads always seem relevent, yet the CTR on a good day is often 15 to 20 times (1500 to 2000 percent) what it is on a bad day. The number of page impressions and clicks is not astronomical but should be sufficient to make these numbers highly unprobable. I'm not a mathematical genius, but I know enough to know that what I'm looking at is highly unlikely.

If you have less than 1,000 impressions/day, it's possible you'll get these CTR fluctuations all the time. CTR will be leveled by increasing impressions.
