Some of the questions I have are not so cut-and-dry as is this thread.
I measure my graticule, that's how far I go.
Nothing will help you spot distortion, like experience. It takes a keen eye, and you have to know what to look for, obviously.

How is "gauging 30%" as you say "ball parking it", when you measure the signal. The graticule is the reference point, so no guess work needed! This is "well-understood".

[QUOTE="LeapFrog, post: 576125, member: 46697"] Some of the questions I have are not so cut-and-dry as is this thread. I measure my graticule, that's how far I go. Nothing will help you spot distortion, like experience. It takes a keen eye, and you have to know what to look for, obviously.
