Earl,

It would be possible to have a spreadsheet or computer program that would give you the adjusted scores on the Callaway system once their score for each hole is entered. I don't have one though. The "formula" (calculation method) you're looking for is explained on this web page: http://golf.about.com/od/handicaps/l/blcallawaysys.htm There is a bit of work for the official scorer to do. My opinion is that it would be easier to do it by hand if the tournament in question is relatively small, say 75 people or less.

Best of luck.
Victoria
