Changes

I evaluated the real -world accuracy of GPS watches while running over 612,000 miles/919,600Km 000Km and recording over 2550,000 data points as part of my evaluation of the [[Best Running Watch]]es. Under good conditions most of the watches are remarkably good, but when things get a little tough the differences become more apparent. However, '''none of the watches have GPS accuracy that is good enough to be used for displaying your current pace'''. For current pace, the only viable option is to use a [[Footpod]], and my [[Best Running Watch| review of running watches]] lists those that can display current pace from a Footpod while still using GPS for your course. (Note that accuracy is the ability to measure distance, not the moment in time position, though the two are obviously related.)
