This is my first year shooting GSSF and I still do not have a handle on everything. I shot my first matches this year, Conyers,Griffin,Dawsonville and Conyers again and I am still confused on procedures. If they use the Christmas tree arrangement for score sheets, I don't see any purpose of signing into all three stages first. If you sign in at Glock M at 9am and then sign in and shoot two other stages and then come back to shoot Glock M, they put your score sheet on the bottom of the tree. How is this different than if I just walked in cold and signed up and my score sheet went to the bottom of the tree? I just don't see the big picture on this, can somebody set me straight? Thanks!
