Let's not forget what I consider the most unfair IGC CC rule of

all- no actual weight based handicapping. So if I fly a Discus b at

825 pounds and BB flies a Discus a at 700 pounds, we fly with

the same handicap. I would have a one pound PSF wing loading

advantage, which would be helpful anywhere but the maybe the

UK.

Big, heavy guys take note. I weigh 100 kg. BB considerably

less.

The reference weight for Discus a & b is 367 kg. Every 10 kg incurs a handicap increase of 0,005. Yes, there can be a wing loading difference but it's accounted for in the handicap.

Copied from current handicap list:

"The handicap is based on the performance at the New IGC Reference Mass.
If a glider is flown at a mass not exceeding this reference mass it can be considered as operated within legal mass limits.
Where a glider is flown at a higher mass by necessity, the pilot will have to provide documentation to prove that his glider is
still operated within legal mass limits and the handicap will be increased by 0,005 for each 10 kg or part thereof that the glider
exceeds the reference mass. However the wing loading may in no case exceed 38 kg/m2. In addition the handicap may in no
case exceed 1,09."
