Using 18% grey card and false color to set exposure

Hey fellas - Question for ya. I've always broadly managed exposure by using zebras and the histogram to try to keep things things in the middle whilst also minimizing clipping. Now, I'm just starting to learn false color and it looks to be a great one-stop shop tool.  My question is.. if I were to put up an 18% grey card, should it be falling around 50% to indicate proper exposure?

It depends on what picture profile/gamma curve you use. For example, F-log maps 18% grey to 46IRE. Also at times you may want to deviate from the guidelines, especially in high contrast scenes, typically you'd underexpose a bit for better highlight detail retention.
