Old Faithful ICL

I degreed the cam and lining up dot to zero I came up with a 109 ICL. Advanced it 2 degrees to end up with 107 ICL. Using a JP timing set. The cam card recommended a 108 ICL but I couldn't hit that by simply turning the crank sprocket. Am I missing something?

Do any of you guys have similar experience and what did your installed ICL end up at?
