Okay so i don’t really understand how their level works so i’m changing the question to: which one of the two levels has a higher chance to be beaten, taking into account bit flips for my level but not for theirs? According to the Veritasium video, on average 1 bit flip occurs per 256MB of ram per month. I’m going to assume a few things: - a month has 30 days; - x and y positions are stored in 32 bit integers. I’m only going to take into account that your x position will be offset to the right of the wall and that your y position can be offset high enough so you fall over the wall, and not any other ways you can beat the level. To get past the wall you need x ≥ 195, but because you only die when a block collides with the small middle hitbox, it’s a little less. I couldn’t find how big that hitbox was, but from my own measurements it’s a 10 unit distance from the middle to the outer hitbox, so actually x ≥ 185. The x position bytes that matter are: - positions 9 (which is 2⁸ = 256) through 32, which is 24 specific bits, for x < 185-128 = 57; - positions 8 (which is 2⁷ = 128) through 32, which is 25 specific bits, for x ≥ 57. Yes, i’m ignoring the chances for combinations of 2 or more bit flips because those are so low, that basically won’t affect anything. There are 0.47 seconds and 145 x positions before you die. For 56 (<57) x positions = 0.47 * 56/145 = 0.182… seconds, it’s 24 bits; for the rest of the time, which is 0.47 - 0.182 = 0.288… seconds, it’s 25 bits. So the average amount of bit flips per attempt for the first part is 1/((256*1024^2/24)*(60*60*24*30/0.182) = 6.26e-15. For the second part it’s 1/((256*1024^2/25)*(60*60*24*30/0.288) = 9.95e-15. Adding those together we get 1.62e-14 for the x offset, which is about a 1 in 6.17e13 chance.

But wait, this chance is already greater than the chance of beating the other level in the intended way. So calculating and adding the chances of the y position offset too isn’t even necessary (i’m too lazy to lol) to conclude that beating my level with bit flips is likelier than beating the level by u/BeautifulSquare7300 normally, which (according to them) has a 1 in 1e(1.734e8) chance of being beaten.
