Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

AS REPORTEDno primary record reached; this is what the reporting says

Is it true that in circular motion, a positive angular velocity represents counterclockwise motion, while a negative angular velocity represents clockwise motion?

Yes. Standard physics convention dictates that in two-dimensional circular motion, a positive sign represents counterclockwise motion and a negative sign represents clockwise motion.
