LODGroup: Percentage?

I don’t rellay unterstand how the LODGroup component works.
The slider shows percentages…of what? Pecentage that the object is visible on the screen? That can’t be correct because often wehen the silder is on 100% the object is not 100% on the screen (maybe 95%). Or do I missunderstand anything?

What are the percentages referring to?

I hope someone can clear things up. thanks.

It’s the percentage of the total view that the object occupies. You can find a nice summary with illustration here.
