I'm not sure, but I'd say e.g. a game with 50 runners will last for 49 rounds, no matter whether they start with 5.000 or 200.000 points, as long as there will be only one fall into the pond per round. ;-)
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
