I went to the garage to inspect several cams after your post. I was unable to see any offset when comparing the Lotus 107 to a JH regrind. The article in question states a 7 1/2^ offset which translates to 3 3/4^ on the cam pulley.
This is about 100th of 360^ and I visualized an analog clock where this would be 36 seconds of movement on the minute hand. Not a easily detectable amount without accurate measuring tools.
I may take the cams to the machine shop later this week to have these things measured and put this issue to bed.
