The unreduced callings contain every row four times each at handstroke and at backstroke, with half the 65s appearing at backstroke.
To avoid falseness care must be exercised in choosing which singled-in courses to omit when reducing the length to 5,040.
While the 5,760 is true to more esoteric methods, the reduction to 5,040 is in general only true to methods with the usual lead ends and lead heads, palindromic symmetry, and usual flow of in and our of course rows.

5,040 rung to Cambridge at Edwalton on 3 April 2015, conducted by Graham R Hayward.
