How does the number that shows in the history file transfer to the imp accumulator and show in the box top left. Why does the number in the box show - NS as 10.2 and E/W show as -10.2 when the difference in imp points in the history section show the total of 19.2 for N/S and 9.0 for e/w a difference of 10.2. In the accumulator box showing 1=10.2 and -10.2 is a difference of 20.4? Thanks. Rich Clark email 43richclark@gmail.com
