-Most keyboards poll for inputs at a frequency of 125hz (every 8ms) or 1000hz (every 1ms) while a few especially poor performing keyboards poll as low as 62.5hz (every 16ms). The polling rate of a keyboard means that //there is a delay from when one presses a key to when the key event is registered//​. If the polling rate is 125hz, then a keypress could take up to 8ms before the keyboard relays the event to Etterna to judge it. The Marvelous judgment window is 45ms wide (±22.5ms), so 125hz keyboards will only have 5 to 6 polling "​slots"​ inside of the Marvelous window spaced 8ms apart. Hits that are early may end up registered by the earliest slot in the fantastic ​window instead of the latest slot in the Perfect window; this would yield an incorrectly judged Marvelous. Hits that are late may end up registered by the earliest slot in the Perfect window instead of the latest slot in the Marvelous window; this would yield an incorrectly judged Perfect.+Most keyboards poll for inputs at a frequency of 125hz (every 8ms) or 1000hz (every 1ms) while a few especially poor performing keyboards poll as low as 62.5hz (every 16ms).

 A 125hz polling rate isn't large enough to affect players that are attempting to get Marvelouses instead of Perfects, but it is large enough to affect players that care about where inside of the Marvelous window a hit registers. Accuracy-focused players that target AAAAs need 1000hz polling rate keyboards to perform well, and they will improve significantly by switching from a 125hz to 1000hz keyboard. Players that push for AAs or AAAs will not be greatly limited by a 125hz polling rate. However, players that feel limited by poor feedback from 125hz keyboards may still improve by switching to a 1000hz keyboard. A 125hz polling rate isn't large enough to affect players that are attempting to get Marvelouses instead of Perfects, but it is large enough to affect players that care about where inside of the Marvelous window a hit registers.
