predict wind

[Guest]

so trying to set up my own polars for predict wind.

 

I find that every time I change any data and then select go it flashes up that I need to enter data in red fields?

 

So I cant see any red fields other than the box with the polars in it and its complete.

 

any idea's?

 

If I log off and back on it saves some settings and works but the moment I change a single number in the polar field same issue.

 

Has any one had much success with using this eg white island etc and was it accurate? or even close? or did good luck and a keen eye and experience pay off over computer generated course?

 

Keen to hear your thoughts.
