max,
since such mathematics seems to interest you, shouldn't the Part 29 certificate of the Super Puma series be revoked, considering the several main rotor blade failures have occurred, even though they were erroneously certified to the same "extremely remote" standard. And now the newest main transmission complete structural failure has appeared, where they also failed the original promise of "extremely remote" failure by the manufacturer.
It seems logical that what is good for one is good for another. Not to me of course, but perhaps to you. Frankly, I believe both aircraft are fine.
