Let me clarify a few things:  I do not shoot Velvia as
ASA 40, but I have noticed that quite a few photographers
do, judging from the captions I read in photographic 
magazines.  I assume that their meters are accurate.

I don't use lightmeters often (especially now with my RBT S1).
When I did use a lightmeter (with my Realist), I ignored any 
decimal parts and exposed to the nearest full f-stop.  With
Velvia I usually went to the next f-stop up (more exposure).  
When I bracket, I do so in full f-stops.  So ASA 40 does not 
mean anything to me. I also don't use tripods as I prefer
spontaneous hand-held snapshots.

"Perfect exposure" for me is a relative term as it depends
a lot on the viewing method.  How are you viewing your stereo 
slides?  In a battery-operated viewer?  What bulb, illumination 
scheme do you use?  Do you project?  Some of the slides that 
appear to be well-exposed in a hand-held halogenized viewer,
look too dark when projected (no all, some do, others don't).
