It was my experience that in order to drive deep and keep up any speed at all you had to come in off the wire and power up a little, the question is when if ever is this a good idea (in racing only).

or would you double trap, power up and go as fast as possible jibing every mile or so. (at what wind speed?)

then again it could be that you have an sequence based on wind speed to edge downwind, such as first sheet out, then come in off the wire, ease downhaul, whatever.

My plan in the past has been to power up as much as possible then depower only when the wind gets a bit wild. this will bring you far away from the rumb line and you must jibe back. When is fast really slow? in real light air you would never do this but where is the line that it is time to heat it up trap out and get your groove on.
