Oh yes, they will permit it outboard of the elbow.  Provision for chord
variation appears to be one of their critical functions, as an
anti-flutter, anti-bistable device.  It may not be happening in quite
the way you anticipate.  Inboard of and near the elbow, I don't think
they permit it to any great extent.

All be best,
