Thanks for reminding me that. I've implemented 'full polars' for the RdR race, but have to port it for the other races too.

Thanks for the heads-up Cvetan!

Cvetan,
the correct polars would be very important.
Please!

10.6*1.852 = 19.631. You caught the partial program change.

The polars should be exact now, and the suggested sail too.

SHOULD is not always the same as ARE, so let me know if you see any differences.
