How To Access LOD?

Hi there,
I want to know how much of a Mesh Renderer is exposed to the camera. 50%, 10%?

A likely solution I have found is Unity's LOD Groups, specifically the LOD Group Selection Bar, as it seems to provide a detailed and accurate account of this, in the inspector.

Trick is, I am having difficulty accessing this value via my code. So, how can I access the LOD Group Selection Bar data?

Thanks

 

There is a

.size

component on the LODGroup object... does that help you? Not sure how that value should be interpreted and I've not used it personally.
