I did some experiments with a script. I found a 14 sided mesh object, the mesh has faces for 7 squares and then 2 face for the other 7 squares. The LI is 1 for the object, and a 7 sided flat mesh is treated as .5 so two would be 1. also an eight sided mesh is treated as .5 also so 2 of those would be 1. When I did the experiment with the 14 face display mesh, it was 7 sides with 2 links even though it was a 1 prim mesh. the 8 sided display mesh is technically 9 sides but the 9th is not rendered. This is speculation, but it might be a limit of the rendering or of the lsl itself
