It is a tedious process when you start, but certain things that come
up frequently make it easier.  2 checkers "opposing" each other total
25.  Bar and 8 point checkers total 15.  The midpoint is 13 times
whatever difference in number of checkers there.  I count the two
outfields and take the difference, and then add the two home boards.
Most of the time I get it right.
I think.
