The polars of several boats have been updated, are they gonna be taken into account in zezo ?



VR announcement :

bonjour afin de corriger le problème de recouvrement voiles pro / voiles standard qui posait problème dans certaines conditions. Les polaires Class40, IMOCA, Ocean Fifty, et Mini 6,50 ont été légèrement modifiées.
d'autres polaires pour Happy (Olympus),Caravelle,Super Maxi 100,Tara et Cruiser Racer vont etre aussi mise en prod prochainement .

Thanks. I'll take a look.

It probably won't affect the routing too much. As I see it it's about the crossover points where a Spi sits between HG and LG at certain wind speed and auto sails give you double penalty.

The 6.50 polars are fixed in a strange way. TWS extended from 50 to 70 knots, but speed above 50 set to zero.

IMOCA from the current Fastnet looks the same as in 2021

Didn't notice lots of zeros when I downloaded the JSON, so I took another look and in addition to the zeros I noticed this:
Argh. I don't think VRDashboard and Bitsailor handle this correctly :-(

My copy from yesterday says

"label": "mono/mini_6.50_v2",
"tws": [0, 6, 8, 10, 12, 14, 16, 20, 24, 28, 30, 40, 50, 60, 70]

but the last two elements of the speed arrays are zero
