One other thing that might be coming into the equation
is a reciprocity correction Olympus may have built in for lower
shutter speeds.
Anyone know if this is true?

If it is a film reflectance problem, then most of today's films are having
a reflective index lower than the old days when OM started the OTF design.
I cannot find any film that give me same values in auto and manual mode (at
least 2/3 stops different). But when the shutter speed is above 1/60, where
auto exposure read the shutter curtain's reflection instead of film, the
values of both auto and manual are exactly the same.
I shot 950f negative so I didn't found out this problem before. But I
always under estimate the speed and got un-sharp shot when I expect I can
hand hold the camera at 1/8s (the 4Ti's meter told me) but eventually it
exposed at 1/4s.
I saw some people said they also observed this but "the exposures have
always been spot-on". I think they can try to shot in both auto and manual
mode for the same scene then they will know what happen. If they got the
same result then this problem may be happen on some production batch of
OM4Ti only and I am the unlucky one.
