Has anyone else experienced something similar to this. Just for a comparison I had my 910XT and my 810 on my bike during my ride today. The 810 recorded my distance at 36 miles with a top speed of 27.9mph, the 910XT recorded my distance at 58 miles with a top speed of 79.5 mph. The 810 has the accurate information. Both of them are hooked up to the same sensors, Vector Powermeter, and the new version of Garmin's Cadence and Speed sensors.
I realize no two gps units will record the exact same distance, but a 30 mile and just over a 50mph discrepancies? Both of them have the latest version of the software from Garmin, and when looking at the GPS plot on Connect they match up. Looking at the other numbers, the HRM information is nearly identical, as is the Powermeter data, and the Cadence data. I'm assuming the speed sensor is the problem when it comes to the 910XT, but that's just strange to me.
