Is frankfurt plane even correct

[NoReedemingFeature]

I think it's unreliable, because I believe having higher set cheekbones is marked on the cranium and so the whole ear and tragus would be higher up.
Thefore aligning the tragus and glabella would still result in different dorsal rotations for any other skull depending on cheekbone setedness.
Is this right?

Just use it for before and after or measuring ratios

I'm trying to overlay very different skulls onto each other for a comparison
