I take it the BE 400 has the range to go about 700 nm, fly the approach, miss and return 700nm with a dry footprint on the diversion? Or does it have 2 hours holding fuel after a 700 nm flight, assuming your rules allow island holding? Or are you flying to the depressurization ETP outbound and committing to landing at BDA an hour from touchdown? While the weather can be very good, most of the time, it can be very changeable and no one plans BDA w/o a diversion to the mainland, usually.
In the Citatipn II we committed approaching the TOD.
