The prsenter of Maxsea said that this routing module is only usefull for trip longer 70 NM. For short distances it of no importance to know the better routing.
The example he showed was just based on wind and streaming forces / directions. The calculated route is made up of one track which is broken into several waypoints where to go.
The so calculated route seemed to longer than the shortest way but as streaming and wind was considered at the different waypoints and the ETA the longer route ( a bend curve) was faster because of streaming and wind advantages!
He didn't say anything about preformance sailing.
