BGA Ladder Handicaps - need details

[Papa3]

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.

Thank,

I'm guessing the figures in the BGA datasheet were used:
