I've read contradicting reports that lateral acceleration is and isn't
an accurate indication of slip. The inclinometer ("the ball") in a full
scale/manned airplane measures lateral acceleration.
I've read that gliders use a string on the canopy instead of a turn and
bank indicator.
Can you have that ball dead center, and still be slipping?

You can fly in a a yawed condition, with the ball centered. Try it!

And there I was thinking anything lateral in a slip was a bit on the
side
