Sorry, a better answer would be that rake should be set for upwind/downwind performance before being set to prevent nose-diving as its effect on nose-diving is practically nothing.

The only influence on nose-diving that raking the mast aft has is to move a little bit of weight aft (mast and mainsail) and very slightly depower the rig (in a similar way as sheeting the main in downwind). Both these influences would be close to immeasureable and would be far outweighed by a rig tuned for upwind/downwind performance.

PS. The reason I say upwind/downwind performance is because H16's don't have kites so the rig should be raked for performance over the whole course, not just upwind. I'm sure there are tuning guides out there with the optimal rake for certain conditions.
