IMO, you should be, first, picking your angles based on strategy and lay lines to the mark or destination, and then subsequently maximizing boat speed at that chosen angle.

In other words, “sail to target speeds”.
Figure out how to tell the difference between direction headers and velocity headers. How you drive and trim is different between the two.

Google “velocity header target speed” and “sailboat target speeds”
Great point. My instruments use a waypoint for VMG wind has nothing to do with it. Whatever factor improves the VMG it will show... upwind or downwind or no wind.

pay attention... someone's life depends on it
