Two things :
(a) 5 out of 10 points is a half win which is what the repeater is receiving
(b) The one repeating is not in a dominant position as those in a dominant position have no need to repeat and claim draws rather those whose positions are falling apart like watered bread or those who have to in order to not lose they repeat thus making their positions weaker than the person being repeatedly checked. Also why repeater should get 5 out of 10 and non-repeater 9 out of 10 .
I've been an arbiter watching K+P vs K games where the lone K player is the one calling the three-fold repetition of an opponent that didn't want to admit it was a draw. In scholastic tournaments it is common to call three-fold on a player with K+Q (versus lone K) when the K+Q player is clueless and does not know how to checkmate. In those games does the lone King player really deserve 9/10 of a point while the player with additional material only gets 5/10.
What about when the arbiter calls five-fold repetition when both players are shuffling pieces in even positions while hoping for an opponent's mistake that would give them a win.
Should we leave it up to the arbiters to decide when a player gets more than 5/10? After all, didn't the 46-game unfinished Karpov-Kasparov world championship match show that arbiters are never biased?
What about the GM draw openings that bypassed rules against draws before 30 moves? (by playing into well known positions where both sides are forced to repeat to avoid losing)
I think the rule should balance the efforts and capabilities of the winner by material with the smart loser who found the threefold repetition in the first place.
Example : Instead of 1/2 - 1/2 , there should be a system where games are given rating points out of 10 lets say and the person winning by material gets 9 of the 10 points and the person who found perpetual gets 5 out of the 10 points . This gives the loser a draw and the winner a winning accomplishment based on effort .
In my opinion, if we're including half-wins, the one checking in perpetual check gets the half-win.
They are the one chasing the king so they are clearly the one in the dominant postion.
