Nice little math lesson. I've encountered this but also didn't give it much thought because no one really cared. It's been more about, 'how fast can this be knocked out'?

In After Effects the Fast Blur filter gives the incorrect result, but Camera Lens Blur filter gives the correct result. This would be why the Fast Blur is fast. ;)
