> The governments stats basically have to be kept. Running the system requires all of the necessary data to already be collected for other purposes, and their stats are drawn from that.
You trust a government entity to accurately report data that's not in it's best interest? When has that ever happened?
Can you explain what your criteria would be for a trustworthy source?
That's essentially the definition of a think tank. This one was founded by a libertarian and considered by many to be libertarian. Certainly cause to question their stats, and I didn't like what I saw.

This is probably enough for you to question their stats, but you've done nothing to show they are wrong.
The stats you provide are collected by an institute looking to further their ideology. They come from a far smaller data pool,and their collection method seems rather suspect. For example, they're asking the actual practitioner rather than anyone involved in scheduling.
