Dear Aldo,

thanks for sharing the CZ handicaps - at least around the 120 index point range it makes intuitively a lot more sense than the icreasingly bizarre DAeC list (which can only be used within a class and not class-spanning, which almost randomly penalizes ships by 3 points in case the DAeC is not satisfied with the availability of a particular polar etc). Do you by chance know on what data our Czech friends are basing their handicaps on? Manufacturer polars? Idaflieg polars? Large data samples from Competitions? Specific weather models/assumptions?

Best regards
Marc (S2)
