I am working on a new polar for my Silent-IN in See You. I have the data
from Alisport, but the question that I have is which numbers to plug in
to
the See You Polar tool.

I have tried several different sets and get significantly different a. b.
c. numbers in See You.

Any guidance on which pairs of numbers, speed plus sink rate would be
helpful.

Min sink? Best L/D?, .............

After you use the tool, it defaults to 100, 120, 150 kph. This might be
high for my lower performance bird.

Thanks
