... Are we talking about the butt end of the cue being 10" off the surface of the table, with the tip angled down to the center of the CB? I looked at this on the table today, and it sure looked like more than 10degrees... ...
Most people are not used to estimating angles of elevation.
The elevation distance you need to measure is how much higher the butt is than the tip. If someone is playing slightly below center on the cue ball, the center of the tip is maybe one inch off the table at contact. If the stick is over the table, it is easier to estimate how high it is. Maybe it is 9 inches from the table to the center of the bumper -- about a hand span, thumb to middle finger. That would make the butt 8 inches above the tip. Here is a table for 58-inch cues:
Elevation is height of the center of the bumper above the center of the tip:
