Have been doing this once every 2 to 3 weeks to see if I can beat my times. My original attempt I mentioned I took over 15 minutes, but I didn't have an accurate timing since I didn't time it and only had snippets of video to go by. But I think 15 minutes was a bit ambitious since I have improved somewhat and my latest time was 17:05. I am slowly getting down to the 15 minute mark, so once I get there I will set the bar at 10 minutes. Consider this a milestone. I will try to keep a record of each attempt to see how much I am improving my time each week.
