Just one more thing!
Pandora, 411A has already outlined a possible way to reduce fuel requirement en-route, when you say you were 3 mins away from a MayDay does that take into account any possible provision in your Ops. manual for reducing reserve fuel prior to arrival at your destination?
The sort of thing I am thinking of is:
"When not more than one hour from destination the wx at destination is CAVOK, two runways available, ATC have advised no delays expected, wx expected to remain CAVOK for at least an hour after ETA etc. etc."
Then it may be possible to use your diversion fuel as en route burn BUT the Capt. must discuss all this with you first, maybe he was trying to be clever and keep it up his sleeve? Very bad CRM but there will always be a few out there! If you do one day decide to talk to management be absolutely certain you have covered all the possibilites.
