Since the German Aerospace Center (DLR) owned an Open Cirrus once for
comparison in Idaflieg polar measurements, the Cirrus polar should be
very well known.

I own a Open Cirrus and was wondering what polar I should be using in
SeeYou mobile?
SeeYou has two polars, Cirrus 18m, with a L/D of 39:1 and Cir.L265,
with a L/D of 44:1
The 44:1 matches the Cirrus’s L/D, but I’ve never seen it called Cir.
L265 ?, and when you google
Cir.L265 it shows pics of a Open Cirrus.
Thanks
