Correct zebra value for 18% grey card?

Hello,

I have some experience as a DP for film projects, but I'm a total newbie lighting -and exposing- for video.

So I was wondering about the best way to set my exposure.

For film I use the traditional Kodak 18% reflectance Gray Card. That would be my V zone. I then adjust subjects by spot-metering, trying to keep skin in zone VI (about 32% reflectance) and everything else inside dynamic range.

I'd like to know what Zebra valor (readme, the % that Zebras point out in the EVF -you'd enlighten me by telling what does that % mean or stand for) should the gray card show. 50% maybe?

What about skin tone? Around 70%?

And the IRE scale? Is it still useful?

Lots of questoins.

Thanks in advance!

Martin.
