But From Ross's Strava of yesterday shows I did a harder ride. Just in case you want to see our route from yesterday- this is his Strava report. That hill at 20 miles is a 16% and is the one on my Avatar

The other day I had a glitch with my Garmin as well. After I updated to Strava my upload converted to metric system. I opened Strava in my Iphone and all my rides were metric. (my first guess was that I was riding with several Canadian snow birds and they infected our electronics.) But by the next day I was back on imperial numbers.
