I get what your saying with taking measurements at 0.250" I would assume the same rule applies "avg of the 2 measurements in degrees" is ICL?
What error do you talk about using 0.050" ?
Yes, that’s what I’m saying. You are trying to eyeball max lift the way you are doing it. I always go .050 or a bit more on either side of max lift and take my readings. That takes the eyeballing out of it.
I picked .250 on the opening side and .250 on the closing side because it’s more than .050 less than max lift and it’s a nice, easy number. You could use .280 on either side of max lift but I like .250 because that easier for me.
