Polars and routing module

Hello all,
It is said in several places to use the standard polars instead of the full one when using the weather routing module of VRTOOL.
For the Cap-Istanbul race, I configured VRTOOL (ver. 1.94) with the full version on the polars : http://www.estceouvert.com/vrtoutoulz/polars/vrt_full/capistanbul_pro-full.csv.

I placed above 2 images of my routing module configuration.

I asked for the best track to south Sardaigna.

It seems to work fine with the full version of polars.
Is it mandatory to use the standard one ?

Still, I can't make this module work when sailing so close to the wind that tacking is necessary.
The track designed by the routing module avoid tacking and goes at 5° from the wind.


Thanks for helping.
Philippe

The full polars will not give you a satisfying route because the angle of exploration will be too narrow. That's why you'd better use the standard ones.
So, with the full polars, the resulting route will always be almost a straight line, of following the great circle path.

And how would i use the BWR game polars? And will them have that same effect, of a almost straight line?
Do you have a file of those polars?

Thanks in advance!
