Apparently theres a total of 120 points up for grabs in a series irrespective of the length of the series. So a team that wins 1-0 in a 2 test series gets 80 points or something while a team that wins 3-2 will get less. This looks like incentive to arrange shorter series against low ranked teams. Theres also no point difference for home and away series. Looks like a massive loophole
