time to upgrade from S/O - F/O will be in the 6-8yr range when D-F/O Pax recruitment starts
That estimate is much too conservative. Not to mention not nearly agitating enough for this sight. Something more like 8 to 9 years should do. But wait, let's just round up, shall we say 10 years. But hey, we probably need a range. And besides, 10 is mearly a decade, hardly enough to stir the masses. How about 10 to 12 years. Yeah, that's the ticket. That will really get them going. Any takers?
