So you mean that "it seems to us" that the BKR will increase more after a winning streak, than if we won without any streak, so we are wrong.......

But that's not what alanback says: He says that the increasement WITH a winning streak is higher than that of without any winning streak.......
While you say that if you win 5 games in a row (=8+8+8+8+8) then you will have (obviously) more points than 4 wins and 1 lose (=8+8+8+8-8). But this is not what we are saying here..........
