The only thing -with my knowledge of the game- that I find suspicious -at this point in time- is that he never stomped on any koopas in 8-2. Every stream of world record attempts streams I have watched (somewes, andrewg, darbian, kosmic etc.) they stomp on koopas with the new 8 second wait rule. Other than that, it looks clean. (Unless a mod comes in and finds something this is what I think.)

and before anyone says "how come you are tapping buttons when you arent in the game in ur 5 flat" thats my wired hitting my desk because of how my setup is, especially when i was in 8-4 i was shaking

Keys good job on the SMB world record you are amazing this is insane.

Why was the 5 flat rejected?

Congratulations about your world record if it's legit :) I am not an expert in SMB very much, especially regarding framerules or stuff like that. But I've looked into the splits file and it looks fairly legit. Despite few fake attempts (circa 6000 in 6 minutes), the rest (1500 runs) looks fine, The real attempts are correctly spaced, with non-uniform length. I just find it a bit suspicious, but that can happen to be honest.

yeah um gamdin remembered when i changed the attempt count as a joke to something like 6900 or something like that, so thats good

Keys altered his attempt counter one time as a joke. Gamdin and Grape can confirm this happened as we were all in voice chat with him when it happened. That's why it isn't displayed correctly

Why would you do fast 4-2 but not 4-1 FPG? And if you're consistent at fast 4-2, why would you do 8-3 FPG instead of 4-1?

Not everyone is good at every trick, too. Keep that in mind
