I had hoped there'd be a greater number of the prescribed temporary set to share around, so that the rollout would be a bit quicker.

This is assuming the availability of temporary sets as the only limiting factor in the rollout. We don't know how the logistics work. Maybe there are two crews traveling around the regions building the new sets one after the other. In that case, you simply wouldn't need more than two temp sets because only two could ever be built at any one time.
