I haven't downloaded my Garmin tracks yet but I'm really struck by how many of the routes I did differently than you. I chose noticeably different routes on 1, 2, 3, 6, 8, 10, 14, 19. I'd say ( could be wrong though) that there wasn't a choice on 4, 7, 11, 12, 13, 15, which means we only agreed on 5,9,16,17,18 ( and I messed up two of those).
leads to the question was I right, were you right, were we both right? part of what makes orienteering so much fun.
