Why does this version of "Ideal Sync ogg" require you to hit 96ths notes in time?

The module has a screen with 4 colored arrows and a bar.

Press the screen when you are ready to input. A 4-beat anacrusis* is played before the 32 beat sequence begins. Proceed to time successive presses as the module cycles through beats 1-32. Mistiming any beat will give a strike when the cycle ends!

Gather all arrows from bottom to top and use the table to find the lowest value that shares the color with the bottom-most arrow. Continue by finding the lowest value that shares color with the next arrow, but has a higher value than the one from the previous arrow.

Repeat this process until you have gathered 4 numbers from the 4 arrows. Proceed to press the screen to start calibration and input the 4 values.

*4-beat anacrusis = Four unstressed notes played for the Defuser to get a sense of the rhythm before the module starts tracking user input.
