If they want to dispute it they had better do a lot better than turn their GPS on at the start and trun it off at the end. I don't know of many trials where there will not be long stretches of trial where the signals from one or more of the space craft will be severely attenuated because of folage or obstruction will be corrupted by mutlipath interference. In which case the data procossed during that period is suspect and the overal measurment made using those data will be unreliable. GPS is good but it depends on the collection of clear strong direct path signals from the space craft. This would not be the case under the canopy folage, in canyons or deep valleys or on many mountain sides. Truman Randy H Eiland wrote: > points or regional-national mileage credit on a LD ride.
