Previous speed problem

[Nono]

Hi Omar, new user since three days, your soft is very nice!
I have now the name of boats, winds....
but i have a big problem about routing fonction: the previous speed is false!!
I maked a print screen for better comprehension (my english is very bad!! )
Boat speed = 16 Wind=17 ....
and previous average boat speed = 5.7 , 9 hours to make less than ten milles !!!
I dont understand why, i think it's come from my polars, but its yours file! (Vendee12_Polars.XML)
I tried whith vendeeglobevirtuel_pro.CSV and vendeeglobevirtuel_pro-full.CSV but the problem is the same.

Best regards
Nono

hi nono,
I can't see your image, even if I copy paste the adress.
I don't use the pro sails so I can't help you specifically with that.

Something that could explain the bad speed is the boat speed factor. It should be set at 1 or close to 1.

This is an old parameter, used by VR in some races as means of matching virtual boats with real regatta boats. AFAIK it is 1.0
