… and the specs for my Forerunner 301 says the GPS accuracy is within 15 meters,” 95 percent typical.” The footnote to this explains that the device is “subject to accuracy degradation to 100 meters under the U.S. DOD-imposed Selective Availability program (when activated). Accuracy depends on view of sky. 99 percent clear view; 95 percent typical.”

The question I would ask is what alternative technology is there that would measure our running routes more accurately?
