[CR3] & [CR4] Explained
Currently we operate with a rating system ranging from [CR0] to [CR3]. [CR3] is something we deem as fact.
However, some folks have pointed out past [CR3]'s that proved not to be true. The reason is because we used to go up to [CR4]. If you do a search for [CR4] things on Canon Rumors, you'll find a few.
When I changed the rating system, I guess I never thought about the effect that ditching the [CR4] rating would bring about.
Thanks for bringing it to my attention.
