Exposure calibration on D850

Hi,

I want to fine tune exposition on my D850 (entry b7 in the menu)

For that purpose I use a Kodak 18 % gray chart.

I shoot the chart in 3 different modes : spot, central weighted, multizone.

First, I expect to have the same result - the camera should select the same iso as the chart fills the frame - and I observe that multizone overexposes.

Second, the histogram should be centered in the middle at 50, as 18 % gray should give the average exposure. Am I right ?

If I'm right my D850 overexposes a little bit, I have to compensate -1/3 EV in spot and central weighted, -0,5 EV in multizone. I have also observed that I didn't have the same exposure parameters with my D500

regards
