Thank you for the great article! Really valuable one, especially to review on a safety day. Hope more people read it and DZs try to enforce. I would just correct the tracking speeds min/max and time. According to one of my last tracking jumps (in RW suit with booties) my minimum vertical speed was 80 mph (you have 120), max horizontal speed was 150 mph (you have 60) and time was 78 seconds (you have 65). Complete info from my FlySight can be found here: https://skyderby.ru/en/tracks/7893 Once again, appreciate your time spend for writing this article!
