I've often toyed with the idea of playing gold level courses as par 4 courses. Easier to keep track (closer to +/- 0).
But I usually blow up and stop keeping score anyway.
When Ashleigh and I started traveling and we played bigger courses, I'd count based on 3 and she would count based on 4. It was easier for her to keep track of fewer + strokes, and also worked as a rough handicapping system.
