Upset with Degree wheel findings

PRH said
To get the cam closer to 107 intake c/l you would move to the -4(or R4) setting on the lower gear.

The -4 slot goes over the key, and the dot on the upper gear gets lined up with the other -4 mark on the lower gear.

Then recheck the installed position.

This is exactually what I did earlier before I posted my question because I wasn't sure it would be correct procedure!
The result I achieved was an intake 106.5 CL, so I guess I was ok.
