Omega 14 Polar Diagram for wind speed vs. angle vs. boat speed

I went out sailing with my GPS and it recorded my track while I recorded the wind speed and boat speed.  I had some blanks I had to fill in so I used a process called interpretation or extrapolation of values that were outside the wind speed range.  I never knew how difficult it is to hold the mainsheet in one hand and the tiller in another while reading the GPS and trying to take notes on a clipboard that keeps jumping over to the low side on each tack like an uninformed crew member. I only drew one side of the polar diagram; assume it is bi-polar for the other tack. (or should I say bi-modal).
