    Brad, I agree with your analysis (and I see that others agree with it too).
    I also got around 400" using the same method as everyone else, writing down pythagorean theorem and approximating tan theta as theta+theta^3/3. The only difference instead of caclualting (1-cos theta) with high precision i used approximation cos theta=1-theta^2/2+... which gives 1-cos theta ~ theta^2/2 without need for high precision.
