I've always been a coward when shooting chrome film for clients. I always proofed with Polaroid. They were all studio shots so I was able to gobo hot spots or fill in shadows. Spot meters are great in checking the range of your lighting. For detail in shadows, I make sure it doesn't fall below 2 stops of my F/stop setting and not above 2 stops of the same setting for highlights with detail. Neg film is much easier to shoot and you can get away with an "average" of your exposure.
That is equivalent to the near-top range over-reading of my Pentax 67 (5 stop range from centre), so I am assuming there is a fault with the meter.

Another vote for the hand held meter. I bought mine when I was shooting 35mm. When I stepped up to med. format I needed no metered prisms. Later I stepped up to LF. Still using the same Minolta auto IIIF.
A good, used Luna-Pro F would be a good choice: http://www.keh.com/camera/Light-Mete...990227390?r=FE
You have three options, (1) uprate the film on the meter and do some test exposures keeping notes until you get acceptable results with slide film,(2) get the meter checked serviced and recalibrated ,(3) buy a hand held meter.
