True, although if mentioned without reference to a base, "normal" often
means "absolutely normal." (i.e., "It's normal in base b" obviously
doesn't mean absolutely normal, but "pi is thought to be normal"
probably does.)

Ah, it appears you are right. Champernowne and Copeland-Erdos are known
to be 10-normal, but not known to be absolutely normal.
