Hopefully someone from across the pond can help out. I'm in the
midst of a discussion with someone about the handicap for the
SZD-55. The debate is on what reference weight is/was used for the
handicap. Can anyone tell me the reference weight used to establish
the handicap? The link on the BGA ladder just shows the index
number.
