In a thread about the manual being wrong, you correct yourself based on what the manual says?

The only way to know is to test it. The manual is wrong about 90% of the stuff that actually gets tested.

Things only get tested if someone has a reason to suspect the manual is wrong, but I'd say it isn't higher than 66%. One in three tests not proving the manual false is about right IME, and then there are all the things the manual just doesn't mention at all, like what kinds of quickness stack with each other.
