This was an exceptionally long transport, far beyond the normal range of even a high performance aircraft. The best way to put together such a long transport using general aviation planes for this distance is to not look at it as a single run, but a number of sequential short leg transports.
With the successful completion of each leg, the next one can be done immediately, or ASAP, or whenever a pilot for that next leg becomes available. What is important is not to set up a run like dominos, so that any problem at any point knocks all the dominos over.
I'm sure there are reasons for any transport to stop or be rescheduled (I have one on hold now awaiting a pup to get beyond a health issue) but if there is anyway to make progress, even if it is one leg, take advantage of the opportunity. Rescues along the way provide that possibility, and from a pilot's point of view there is never a need to be feeling pressure.
