The rules state that "... [Time] ends when 100,000 points have been accumulated." However different versions of the game will have a start value in the score box depending on the difficulty selected.

For instance, the GBA version of the game will have 100,000 points in the score box when you start a game on Normal difficulty. That would technically be a 500ms run.

I suggest the rules be changed to state that the run: "ends when 100,000 points have been accumulated on top of the starting score."
