I do need to keep that left wrist flat but say, do I cover the base line of the plane or trace it?

Thanks!

Trace it - do some flashlight work to get the hang of tracing the plane line with the imaginary line from PP#3 through the sweet spot. I've found the perfect flashlight for this - the Streamlight Stylus Pro, which is about the same diameter as a golf shaft and about 5" long, and takes 2 AAA batteries. Your hard work will surely pay off!
