We analyze two races on the same day and show just how much it changes your race to try and punch through headers, instead of tacking in them. With raceQs' built-in analytic tools, it's easy to see how the decisions you make on the race course affect your race statistics and overall performance. Missing just one header can change the geometry of the entire upwind leg as you sail sideways across the race course, instead of making the progress you need upwind.
