In fact they have absolute mathematical validity especially if compared
to the computers divers like Feesh use
ie that one between their ears which are even unable to
do some simple calculation  like 2+2 if a little narced.

The Orca was used by my grandgrandfather during the Worl War One for
dives no deeper than 10 metres.

They are a revolution in the dive technique.
