Indy,
You are correct, the idea is to get people together, this isn't a Pony Express Reenactment! It's also a good idea to build in a wee bit of pad time so that weather and other issues can be dealt with while not compromising fun, safety or the overall plan.
The worst case scenario, IMHO, is to advertize a handoff date, have persons downstream schedule vacation based on that date, then have to miss the relay completely because they can't change their time off if Godzilla doesn't hit his marks.
I don’t think we’re in danger of the PacNoWest riders having to deal with fall weather… YET! Nor are we in much danger of clashing with the August bike events in Eastern Canada... YET! Like I said, a wee bit of pad time, more so if it means dozens of riders can participate.
Do show Godzilla a "Good Time" while on hiatus!
