Confessions of a Lane Five Swimmer - Part 2

I am settling comfortably in Lane 5. I can keep up with the lane during 50's and strokes. If we do 8 x100, then I line up toward the end. But if we do 150 or more, then I fall behind. I still need to find my comfortable zone that I can pace myself out for 200 yards and be ready to move right on to the next set.
