If you use the cylinder without getting into the sector you get a 1km
ditance penalty for each TP which is more than the distance you save by
using the cylinder.
Sporting Code 1.2.11.


Be aware that A given SOARING PERFORMANCE may use only one type of
OBSERVATION ZONE (OZ). The shape of OZ may be either:

a. a SECTOR OZ (1.2.9),or
b. a CYLINDER OZ (1.2.10).

This OZ may only be used when a FLIGHT RECORDER is used for
verification.

See Sporting Code section 1.1.6.
