The existing ELO calculation after a win (or loss) treats the result as a win (loss) against each of the opponents, **and a tie with the player's partner**. That means that if you are paired with a weak player, ot only is winning more challenging (which is fine, luck of the draw) but also your ELO is docked because of partner's weakness.
As an extreme example, say a 600 is paired with a 20 ELO, playing against a couple of 310 ELO opponents, and everybody has K=20. If the 600/20 team wins, the 600 gains about 4 points against each opponent, and ties his partner, which is about (-18+2)/2 = -9 ELO points. The sum is -1, so the expert player, having beaten a couple of strong players despite being paired with a beginner, would *lose* about half an ELO point. Since the odds of winning, based on linear approximation using the combined ELO's, were about 50%, that expert (and his partner) should have gained 10 points.
The best solution is to treat the game as a two-player game, using the pair-averaged ELO rating for each pair to determine the effective ELO. If that is awkward within the overall BGA framework, then at least the system should not be indicating a tie against your partner. -
