Clearly OP is able to complete 41 points per week. If low performers also did 41 points per week, are you saying OP wouldn't do 41 points per week?
Assuming tasks are unlimited, to OP's perspective, the entire team should be doing 41 points. It isn't that he is doing 'their' work.
I think OP is upset that he delivers more work, but is still paid the same. Companies reward the extra work via promotions and bonuses.
