If you change a win of 1:0 to 9:0 for the new method, then you
immediately understand the old method is way better.
When your best player is out for 3 weeks, the new method almost guarantee you a total loss for the three weeks, the old method limits such an impact to the minimum.
On ztyixia's comments about the new method being better: no player is not prone to injuries in the middle of a week, but its likelihood is the same to all teams. Only sees your own teams's bad luck is like seeing the empty half of the half-bottle water.
Unfortunately, it is 6:3 in favor of win-by-all. hohohoho, Laosha must be a lazy-bone.
