Cam degreeing help me understand!

Can I ask a stupid question??? When there is an advance ground in to a cam, that will be the measurement at the lobe. Correct? Anotherwords....my cam card states 106 intake and 114 exhaust. That should be my actual measurements. No? I guess I am not understanding the "ground in". Is my cam 110 with 4 degrees advance ground in giving me 106? What about the exhaust lobe?
Does advance get ground in there as well? Also, when a cam is advanced or retarded via crank gear or offset cam key, the exhaust should move the same amount of advance as intake. Correct?
