My point about being a line pilot was just to put my words in the proper context. I agree with you that we do not have much experience with textbook diversions, i.e. a go around followed by an immediate diversion. However on the few diversions I've had, fuel burn was not really a factor and ATC was very very helpful after some prompting, giving direct routes to the FAF.
I do take on board your point about possible inaccuracies in the alternate fuel calculation, but as pilots we also hold a lot of the cards in our hands. Don't be afraid to assert your position as a captain. If you do not get from ATC what you want, throw out a PAN if you think their dithering might lead you below Final Reserve. Sometimes ATC are bound by certain protocols or airport managers who are slow to provide information regarding the acceptance of your diversion. Once you throw out a PAN, they will gladly co-operate and you become their number one priority. Use the system as it should be used.
