Oakland University here in Rochester will be hosting the Great Lakes Div. I Regional in a few weeks. After reading the study that Justin posted a few days ago, I suggested to the coach that we might want to look at how his wheel is going to calibrate on different surfaces.
With that in mind, I borrowed his wheel (and also took my own) and headed off to the golf course. Here are my results:
The surprising part for me was the difference, which was very consistent, in going one direction and then the other. As can be seen for both the rough and the fairway, the uphill walks gave a smaller measurement than the downhill walks.
I should mention that the "rough" was really more like a well manicured lawn with short, but not thick, grass. The fairway was more like carpet than grass.
Finally, I included only 1 decimal of precision because I was estimating the fraction of a wheel turn when I got to the end of the course. When we calibrate in preparation for doing a course measurement, I'll be more precise.
