Which leads to another question. How many tacks and jibes are common in F-16 buoy racing?

From the Tornado I am used to three laps with a race time of about 1 hour for the fastest teams. Quite often, it pays to 'bang the corner' and just do one or two tacks upwind and perhaps some more gybes to play gusts and headers downwind. What will it be like at Zandvoort?
