Changes

I evaluated the real world accuracy of GPS watches while running over 12,500 miles/24,800Km 000Km and recording over 710,000 data pointsas part of my evaluation of the [[Best Running Watch]]es. Under good conditions the watches are all remarkably good, but when things get a little tough the differences become more apparent. The table below is a vastly simplified summary of the results, rating the best device as a 10 then comparing the others. (Note that '10' does not indicate perfect, just the best I've measured so far.)
