I went from first movement, standing start. It was an experiment that worked perfectly for my 4 girls. The boys times weren’t on the table and I had to make some adjustments based on the table progressions. Considering I am a math teacher this was quite fun and interesting! Maybe DDR athletes who used this table had beam timed splits back in the 60s and 70s (book was written back then).
Overall, the boys time dropped 0.8 seconds Saturday off their previous season best.
Chris, I do like your idea of exchange zone games. I have felt some athletes don’t get out well. I think this will be fun to do in the next two weeks to get prepared for the bigger meets of the season. My kids don’t get enough races in the 100m through the season and I’ve found it hard to see nice drops in time. Most many run 3-5 races only. When I ran, I counted one year I ran 15 100m races in 12 week season, which may explain why for two years I opened at 11.4-11.7 and ended at 10.9/10.8. My kids opened at 11.9 and may break 11.4 if temps are warm. I say this because I think the only way the relay times will drop much will be mastering baton velocity.
I also think you are on to something with the turn times. Next year as part of my testing, I will include a lane 2 trial standing, and lane 2 trial from blocks.
