What I've noticed on my site is that after I pass 3,000 page views for the day my eCPM plummets. My page views are normally in the 2,800 to 3,300 range. As long as I stay under 3,000, my eCPM will be in the $31 to $33 range. When my page views are up around 3,200 or 3,300 my eCPM drops to around $27. This has been consistent over the past two or three months.
Last night I was at 2,900 page views and had an eCPM of $33. It had been above $30 all day. This morning I see that I ended up with 3,400 page views and an eCPM of $27.

My server stats for page views match up pretty closely with Adsense throughout the day
But you missed part of what jchampliaud said: "What if the page views and clicks stats aren't updating at the same time?"
Page view and click stats do not update at the same time throughout the day, so any hourly or daypart analysis is basically worthless as we don't see the actual numbers for that moment. The only reliable numbers are the ones after the day is complete, when all of the page views and all of the clicks are included.
You have to remember that Google has a share on whatever you earn - so the bigger your earnings, the bigger their share. That's why they release heat maps for optimum ad placements, that's why they do optimization calls to high earning publishers - all in the name of maximizing revenues. So the mere idea of Google putting a cap on a publisher's income is downright ludicrous.

So its probable that the 3000-3200th Ads shown are worth less than the 1-2999th ads. The lower value drops your eCPM overall.
I have seen no proof of Google controlling the amount of profit you can earn.

The main point is that it is counterproductive for Google to put a cap on a publisher's earnings. Why? Because they are essentially putting a cap on THEIR earnings, and I don't think any corporation in their right minds would want to have any caps at all in their earnings.
I don't think they're placing a cap on anyone's earnings, but they might put a daily cap on how many ads (or what percentage of ads) from a given advertiser appear on a site each day. That would make sense for three reasons:
1) To maximize clickthroughs (since the value of an ad's frequency drops off after about half a dozen impressions);
2) To keep a handful of publishers from hogging all of the ads in a niche (which isn't good for recruiting and retaining other publishers);
3) To protect advertisers (who wouldn't be using an ad network if they wanted their ads to run on only a handful of sites).
Whether the metrics are updated simultaneously or not is not the point. The main point is that it is counterproductive for Google to put a cap on a publisher's earnings. Why? Because they are essentially putting a cap on THEIR earnings, and I don't think any corporation in their right minds would want to have any caps at all in their earnings. The key is to maximize revenues. And if Google could squeeze out every profit from every publisher, they would do so and NOT put a cap on anyone's earnings.
I guess since this view has been posted numerous times, it makes to much sense to be true. I guess Google really is not under any pressure to increase their revenue?
I for one have not been capped. My earnings increase and decrease linear with traffic. My page views per day average around 25,000 sometimes as high as 35,000 and as low as 20,000
I'm becoming more convinced that Google caps what certain sites make. Now, I believe it's possible to break through that cap but it requires significant increases in traffic while maintaining the same CT rate.What I've noticed on my site is that after I pass 3,000 page views for the day my eCPM plummets.

You are 100% right that Google caps earnings for high earning websites. I have noticed that too. Other factors are also present, for example, day and a time of the day. My average daily earnings plumeted 33% once I crossed $8,000 in February; the traffic remained normal.

My earnings is 3x bigger than your earnings and I DO NOT see a cap in mine. On good traffic days, my earnings is 2.5x that of my poor traffic days (weekends). And the monthly growth in my revenues tell me that the earnings potential grows as my website's traffic grows (assuming I get the same quality of traffic as what I am usually getting).

How is that proof? Just by chance, a sizable number of publishers with level traffic are going to see earnings go up, a sizable number will see it go down, and a sizable number will see it stay the same.
If every publisher who saw their earnings go down after hitting a certain level claimed that they had been capped, we'd have a LOT of caps here.
