At the next IGC Plenary Meeting (29 February through 1 March), there
will be a specific proposal from the IGC Sporting Code Committee to
change SC3 to allow use of COTS GPS in conjunction with barographs for
Silver and Gold badges. May I, once again, suggest that you contact
your IGC delegate to make your viewpoint known?

Why bother with the barographs?

It's rather simple, GPS altitude is not currently an IGC recognized
means of measuring altitude in soaring performances, and changing that
is far more complex than adding COTS GPS as an alternate means of
documenting position evidence.
