Charts must have been the way to go. Goals for on one axis and goals against on the other. 100 on each axis.Very true. I can do arithmetic quickly with pen and paper, but 92 is an awful lot to do (some teams were alone on their points total, so could be ignored). Were there perhaps charts with all the permutations in sequence (eg 25 divided by every number between 1 and 100?)
