Cam Degree Question

This can be confusing. LSA is measured in cam degrees. ICL, ECL & any advance or retard [ eg, 4* adv ] is measured in crank degrees.
If you are using the crank spkt to adv or ret the cam position, that is in crank deg. So if the LSA
was 109 & you used the 4* adv slot on the crank spkt, the ICL has moved from 109 to 105. ECL has moved from 109 to 113. Based on the assumption the cam has no adv or ret ground into it.

I am not sure about slots in the cam spkt. Are they cam or crank degrees???
