It would help crystalize the separate "pressure" version of the game where a 1-stroke penalty is added for failing challenges created by the designer (in addition to loss of distance and sometimes position) by limiting the damage for failing those challenges to potentially just 1 stroke if the player chooses the rethrow and successfully executes it.
And sometimes the scoring in this pressure version of the game would look like traditional golf (where almost every throw counts 1 stroke in a round) in the case where a player always chose the rethrow option instead of a penalty. However, the reality from a game scoring and statistics standpoint, is there would always be the equivalent of a non-throwing stroke in the scoring when players fail challenges created by the designer whether they sometimes take the stroke penalty directly or must count 1-stroke for the poor throw and have not yet advanced because they chose the rethrow.
