Why does Does concept of degree of unsaturation not work for fullerene molecule?

Commonly known buckminster fullerenebuckminsterfullerene has molecular formula C60 if we calculate it's degree of unsaturation by formulae, it comes out to be 61 and it is also known that this fullerene has 12 pentagon rings and 20 hexagon rings.

So, overall it has 32 rings. Also, degree of unsaturation can be thought of as number of pi bonds + number of rings for hydrocarbons, so the number of pi bonds calculated are 29 according to this concept

However, the number of pi bonds in fullerene have been found out to be 30. Why does degree of unsaturation not work for fullerene, what is it's actual degree of unsaturation?
