I have a few questions.
How would you measure how straight up the head went?
In your replay you decap and then throw the head so wouldnt this be the most vertical throw/kick of a head record instead? Should moving uke be allowed?
Here are two of my replays I made a while ago. I move uke in both of them but in one the head goes up right after the decap while the other i kick the head up afterwards. I also spelled straight as "strait" for some reason.
