Let's talk about keyboards and polling rates today. It's a huger deal on games than most people think.

FAQ:
'What is inconsistent polling rate?'
I semi-explain it in a keyboard review here https://youtu.be/2BoRydJWyEo?t=296

'Why don't you just use the keyboard scan rate website?'
Like what their website said, it does not test polling rate. It's not very accurate either depending on your keyboard. It determined my Happy Hacking Keyboard was 33.33hz when it's 125hz, I asked other HHKB owners to test as well and had the same results. So far without buying expensive equipment, Etterna gives the best estimate on keyboard polling rate.

'Is X keyboard 1000hz?'
If it's a gaming keyboard from a reputable gaming company that boasts of 1000hz in their marketing material, it most likely is. Not all gaming keyboards are great, but that's polling rate and chord splitting aside and reaches more of per-keyboard review territory. Otherwise, I don't know and you will have to test it yourself.

'But X player got X best score without 1000hz!'
Yeah, you can still do crazy things without a 1000hz keyboard, but with a better keyboard, at high levels it gives you more hit window space to work with.

Etterna community - For caring about rhythm games and their keyboards so much and for helping out in the spreadsheet (I also think you guys might've had some help behind senya in communicating with me and allowing the spreadsheet to go public). Thank you!
