Note 2: Pannenkoek favoured convenience over optimizing for time. He raised the water so he could copy paste inputs, but he demonstrated in a later video that lowering the water instead is about 9 hours faster: https://www.youtube.com/watch?v=zjdkGWJcDVw Note 3: This isn't always strictly true while sliding because sliding speed is a vector calculated differently from normal speed, but it is true for the most part. More on that later. Note 4: Because he's sliding, he has to make sure to hold the control stick back out to the left or forward. Keeping it to the right would make Mario turn into the platform and prevent him from falling off. This is why, while grinding itself is easy to achieve in real time, dive grinding is TAS only because the stick needs to be in different positions on every frame. Note 5: Technically, the TTM secret slide and the SSL pyramid also have loading zones, but they have no grabbable objects nor interesting objects to clone. Note 6: Blue Coin Clones https://www.youtube.com/watch?v=1GeID2o7CV0 Although the PU glitch was not yet understood at the time, this is nowhere near the first observation of it either. It dates back to 2005 or earlier. Note 7: Specifically, walls are checked once every frame, but not every quarterstep. More on quartersteps in Part 4. Note 8: There is an additional speed type used when flying or swimming that is a 3D vector. Note 9: There are only two goombas in this trio because the third one is the Mystery Goomba: https://www.youtube.com/watch?v=zy4LiwZ3Uqk https://www.youtube.com/watch?v=rEBMaAoKRvw Note 10: The object slots shown here are a major simplification. In reality, these slots are shuffled almost every frame. Note 11: This has since been found not to be true: edge grinding while holding an object can load up to 15 dust particles at once if done right. This is based off the information known at the time.
