At the moment my boat is gybing along at 26.1 kts in around 22 knots of wind.
The TWA is 150 degrees which, also according to WR is "Best VMG".

Looking at the Zezo Polar diagram at this wind speed the best VMG should be at 140 degrees TWA and the boat speed should then be 25 kts, 20.7 kts at 150 degrees TWA. The routing still suggests sailing at TWA 150 degrees. Does anybody know what is the problem here?
Does Zezo and VR use different polars? At the moment there is a very large deviation...

Ooops. I had the wrong polars here - but that only affected the user interface - track tool and polar chart.

The router itself should be OK.

I don't play the game myself and nobody noted it.

BTW it's pretty obvious if you know where to look - with reasonable sailing angles the circles on the projected tracks should line on the isochrone lines.

I fixed the data but you may have to force a refresh or wait few hour before your browser loads it.

Recently converted to zezo use, I'd like discover and understand the way of predicting and compare with personal predicted tracks. Could you live me a link to get the Sodebo Ultim polars ? Best regards
