I always use meters because they are the same for everybody. Counts, revolutions - they change with the measurer and the day.
For clarity I believe that when one speaks of length, one should use solid standards.
I've seen confusion arise when somebody says a course is xxx counts long or short. That information tells me nothing.
If a course is measured on two separate occasions, counts for one occasion will not be the same as counts for the next. Only meters, feet or miles will do.
