The wind was mostly from the East but occasionally the tail of the the flag mentioned would shift a little to the south and sometimes to the north. I was scoring target 4 but was watching the flag and where all the shooters shots went when there was a switch. Almost all were blown in the same direction! I missed a couple calls but was watching the 440 yard flag before each shot and it helped me place 30 in the X-ring from a bipod! I was pleased!
