I think you should say "overriding" wherever it's legal,
but never say "not overriding".  And use a compiler that
warns on missing "overriding" -- such as a recent GNAT
with the -gnatyO switch.

I agree that in the OP's example, P2 should be overriding -- this is a
language design flaw.  But at least you won't get in trouble at
run time, if you follow the above convention.
