I think the answer to your question is that the valve you are adjusting is
actually on the (bottom) round side of the cam lobe when the reference
valve is on the peak of the cam lobe. This means that you have a number of
degrees of slack on either side before the valve you are adjusting begins
to lift on the cam lobe. So, even if your reference valve is a little
before or a little past the peak of the cam, the valve you are adjusting is
still fully closed. (If you use your crank instead of the starter, you can
be more exact). Does this make sense?
