could be a lot of reasons, but I would just think the slow response is normal in a strong wind, I fish a verry windy lake and I get blowed off more than the 5ft. norm. but I just set it and forget it, dont pay any attention to the exact location, but them again I am not to pertucliar on stuff. since I have been using the I=piolit I have found I can concerate more on the fising and not so much on where my foot needs to be on keeping me close to the brush pile, I bet you will figure it out and hope it all works out. I kinda like the I=piolit and hope to learn more about it on here, I will hit the power lines and see what it does, but the way my luck goes, wont be an ounce of wind to test your theory.
