“WL”, or the Wrapper, corresponds to the side of the fitting associat-
ed with the offset dimension used for the calculation. The longest
Wrapper corresponds to the side with the largest offset (y).
Caution: When working with a “Change Transitional OGEE
Offset” (Wrapper size transitions from one end to other) the length
of a cheek having a slant length must be adjusted to include
that slant length prior to the calculations above taking place.
