Any difference coming off the lift is highly exaggerated, a 1 row lead turns into a whole train ahead of the other, 2 rows turns into a train-length lead. Then they do come together some over the big camelback and a lot at the turnaround since the leader slows down first. I also got the impression South falls even further behind on the return, although it should be faster as it is smoother, although often fewer people on it. If South was the side that started a row ahead when the sync gives up 2/3rds up the lift, part of the difference would cancel by the top and they might finish neck and neck.I think this was more than a syncing issue. It did a pretty good job of lining up the trains at the top of the hill, letting us catch up when we were behind by a fair bit, though yes the other train started dropping first. However the side I was on seemed to be running slower as well and the other train just kept pulling away. By the end it wasn't even close.
