Thanks, I did do a yacht race once, and that explains a few things.In general, the boat that wins a W/L race will have the better average VMG
At times the boats sail hotter angles and go a bit faster, and at other times they sail higher/deeper, and go a bit slower. Also, the target TWA will vary depending on TWS, so if boats are in different wind speeds, they will be sailing different TWA's
if you want to look at the stats, they are available for each race. This is the data transmitted by each boat, and VMG is wrt the wind measured on that boat - so when you compare VMG's between the boats be aware that they may be sailing in different wind speeds.
here is the link to the data - just choose a race and the quantity which you wish to plot
