I think it's safe to say that the 2x Solars are ring fenced for the 4 though, as the depot would be snookered should any of the Citaros need to come off the road. MPD or Cadet are arguably unsuitable for the route, and the deckers simply can't be used.
I might be a mile off here, but that leaves a spare ratio of about 9%? 2x single deck vehicles to cover 82/82A/85/86/88/88A. Usual PVRs are 7x Cadets, 4x MPD and 8x Versa?
