Very interested in this as well for standardization. Any update?

Following - I was just doing a test with C70 and Clog 2 and the EL Zone system on my SmallHD. Adding photos for reference. I am finding that "proper" exposure via the C70's waveform feature is reading as +2 stops on EL Zone system on SmallHD. You can see in the two photos when using middle grey to expose established my EL Zone system and then when I do it by waveform.
