Split Lobe Separation Angles?
I'm pretty sure when cam mfr's advertise the ICL/LSA numbers, it's per their intended installation...
e.g., COMP cams likes to have (most of) their OTS cams to be installed at 106* ICL (because they grind them with 4* advance), but of course that is just what they say...the LSA of course, doesn't change as it's ground into the cam. So, regardless of whether you install it at 106* ICL per the provided instructions, straight up at 110* ICL, because you want to, or 102* ICL because you want to (and because maybe you want to boost your low/mid range a little, the LSA is still 110* in the case of most of COMPs legacy OTS grinds.
...or maybe I'm missing your point...?
