I'm not sure Ryan. Ads are entered all thru-out the day so not sure if you are hitting it at those times are not.
The amount of ads at any given day, will vary of course depending on advertisers.
Oh, and that is what I got a few minutes ago at cron run, 7 ads. Some times I get around that amount at
reset time and for me, it's midnight central time zone, I go to bed, when I get up, I will have more to click.
It's not that way all the time.
