C, except for F. 40, invariably puts V. nearer center than F. O moves between 90 and 135, putting V. farther to F. 100, nearly symmetrical at F. 100 and 120, and after F. 120, from 100 to 135.

(1) Curve out.
(a) F. (80×10), V. Curve.
In every case but one V. is nearer center than F.
(b) F. Curve, V. (80×10).
C puts V. farther from center than F. O puts V. farther or symmetrical up to F. 120, then nearer than F.
(2) Curve in.
