Default series tie resolution

If no series tie format is specified in the NOR/SI's does it mean you should default to the RRS ones?  aka

A8 SERIES TIES 
A8.1 If there is a series-score tie between two or more boats, each boat’s
race scores shall be listed in order of best to worst, and at the first
point(s) where there is a difference the tie shall be broken in favour
of the boat(s) with the best score(s). No excluded scores shall be
used.

 A8.2 If a tie remains between two or more boats, they shall be ranked in
order of their scores in the last race. Any remaining ties shall be
broken by using the tied boats’ scores in the next-to-last race and so
on until all ties are broken. These scores shall be used even if some
of them are excluded scores.
