Take a roll in a Nikon F80, 65 or similar. Use spot meter, take representative scenes, make a bracketing for each scene, say -3, -1.5, 0, +1.5, +3, for the "0" image anotate the reading with the spot meteri the interesting areas: clous, blue sky, water, glares, shadows....
Compare the readings from the F80 to the meter you will use for sheets.
Develop the test roll and memorize well, how sky looks in each exposure level, for example if it was at +1 in the "0 image" it would be at the +4 overexposure in the +3 bracketed image.
If you don't have an spot meter you can use a lightweight F65 with the 50mm 1.8 to spot meter, this is a good spot meter, reember the exposure compensation...
IMHO Velvia/Provia require good spot metering, slide sheets are not a joke, and exposure has to be nailed, so it's good to use spot meter to know how how every area will end.
The test with a roll and bracketings is important because each color has different sensitivity in the meter and in the film, so a practical knowledge on how a blue sky should be exposed is very important, also for people's skin with provia...
Then you will realize when you need a NG filter, etc...
With that exercise you will expose slides perfectly, with very good prediction about what you will get.
