I found that if you play using the Sesame Street Fighter Emulator, there is a way to buffer the game. You can switch between tabs to buffer the game. This way, perfect runs no longer have to be luck based. The Tab Buffer, which I will name it, allows you to see the first letter on its first frame when entering the screen. I exclusively run Beat Elmo/Oscar, so this tech helped me secure my current [PB]. However, my computer won't verify my initial press for a few seconds. So can someone please try this with their computer and let me know how it worked? This could possibly change the meta.

But then the timer will need to be real time and not in game time

Then we can double time categorize it. One including the buffer, and the in-game time. Plus, when the meta further develops Tab Buffers could last a split second from the runner.

Update: By mapping the tab management to my keyboard(s) I've been able to consistently get the buffer.

can you make a guide on how to do this GameCrash?

yes that would help
