Sure, anything's possible, and maybe Google is throttling you. But why would they do that? The more you make, the more they make.
I forgot to address this - yes, they make the exact same thing regardless of where the ads are displayed. Whether it's my site or someone elses, they still earn the same revenue.
If they do not have enoug ad inventory to run on all their Adsense publishers, a revenue cap makes perfect business sense. You don't want to 'run out of ads' and have new publishers displaying nothing but Google's own service ads or blank space.
