I think that you are attributing more to Moly-disulphide lubrication
then it deserves. The most common attribute I can find listed for it
is that it withstands high temperatures better then some other
additives. Certainly when I was working on airplanes, courtesy of the
U.S.A.F. it was commonly used as an anti-seize on jet engines.

Anti-seize also equates to an extreme pressure lubricant, exactly what is needed for a bicycle chain where plain bearings are started up under load every time the links come off the top of the rear sprocket and also when they lead on to the front sprocket. Hydrodynamic lubrication does not occur and boundary layer lubrication is the only consideration.


True it has the ability to plate surfaces which results in improved
lubrication but whether it can improve chain efficiency by an
additional 1+ percent may well be less then accurate.

The differences under racing loads are evident to the rider who can only just hang on. It may well be that for short hillclimbs and sprinting, the efficiency variation is even more obvious. Out of the saddle efforts place super extreme loads on the chain which it is not really expected to carry with efficiency, which is where special lubricants kick in.
