I am over 70… so on your program will my driving stats be based on that as a 5 handicap my driver distance is 225 yards? Can I base my rounds on 3-5 handicap or are they based on pro or scratch?

It is most useful to know where you are gaining and losing strokes, and it sounds like distance is one place. There are also two reports that are helpful to monitor: trend reports (e.g., to see if you are gaining or losing distance, getting better or worse in SG in various shot categories) and good-poor round analysis (which compares your own good and poor rounds).
(We will be adding additional benchmarks in the new year.)
