very good. great catch 80. however, you forgot about the grandfather clause in the intro to Edition 2.v5 – also known as the 171rule (72 and 99) in which 72 and 99 are not bound by limitations expounded upon in editions post edition 1.v2a.
Last I checked the edition you quoted from is from is 3.v1… how about some more coffee over here (and no grumbling)…
