Would it not be correct to work out the points per $ redeemed etc, by dividing points redeemed, by the fare amount that would have been paid. In your example the $6,076/244,148 works out at .0249. I calculated what it would be for my LAX-SYD trip at 94,000 points each way (188,000 total), based on the same fare price you paid and it worked out at .0323 ($6,076/188,000) which says that the points redemption in my case would be not as good when it is better by just looking at the number of points used, which are 56,148 less.
Dividing the points redeemed by what fare would have been gives the true redemption value per 40 points per dollar against 30 points per $.
244,148/$6,076 = 40.1824 points per $
188,000/$6,076 = 30.9414 points per $
