What’s up with the choppy mouse movement near the end?

Take 10 more minutes of your time to right click the screen.

Every single category is ~0.5 seconds slower than the runners actually play. I believe that the time should not start when the play button is pressed, but when the first piece is selected. At least categories like "All Difficulties", "All Puzzles" and "All Variants" should be timed with IGN, since it takes ~30 - 180 seconds in the All Puzzles/Variants Categories.

that's bullshit, you just want the satisfaction of beating it again
