I've just noticed a curious side effect to the new vacation system: I have 2 chess games against a very strong player who stopped logging in for the past month. His vacation clock is winding down with 7h to go. He has 33 running games, and should time-out in all within one hour. Now here's the twist: When he times out his first game his opponent will "gain" a lot of BKR, but those "gains" for the opponents will drop sharply as the hour advances, because the player who times out will "lose" rating for each finished game. So the first opponent who "wins" gains a lot of rating points from winning against a strong player, the last one gains less, because the strong player has become mediocre within one hour. Tragic...
