Just a quick question from Newfoundland,
Is Lu's missing 18 degrees, what we are said to teach as advance angle?
I thought the two: Phase Lag and Advance Angle were interconnected. It is a little hard to follow when one cannot read Wayne Johnson's book because it is way too technical for a lowlife instructor like me!
Otherwise though, good posts, very informative and interesting, almost like sitting at Ray Prouty's seminar again!
