Further thoughts on ConcordeX. When I used the "old" system with the small truck, GSX must have been able to access the correct variables because using the timing factor I had set up for fuel load and multiplying it by the required load always came out very close to the time the GSX truck stayed in place before announcing, "refueling completed". And further, since I am still using the previous version of ConcordeX (before the latest upgrade), won't the new GSX refueling procedure, in my case, still access the same variables it did on the old orginal refuel procedure? I am using the same CPS program and, yes the loading of the tanks is non-standard but it has not changed in my case.
