Degreeing Cam by Measuring Overlap @ Lifters

I had Ken at Oregon cam pretty much grind all of my cams and this last time we had an in-person conversation about degreeing the cam in my latest build that he ground... He certainly didn't mention anything about putting a little level across the intake and exhaust lifters...
The whole discussion surrounded getting it degrade to the cam card specs over the intake centerline..
While Uncle Tony and other Youboobers have their budget minded time (very little..) saving methods and especially in Uncle Tony's case justified by it being an old racers trick to save time in between rounds which likely those racers use the same cam over and over you're not going to find any cam manufacturer to say do it with a level across the lifters...
99.99% of the time if you just line it up to dot it's going to run fine, but run to its potential... My money is going to go on what the cam grinder recommends and it ain't sticking no level across the two lifters..
