LineIII (among other things) accurately calculates the theoretically correct leadout position based on an extremely complex equation that first calculates the drag and arc of the lines.

LineIII is an update to Pete Soules LineII with updated user interface and a few enhancements. LineIII was written by Bob Reeves using Borland C++ Builder, without Pete's help and consultation it would have never happened.
Thank you Pete!
