	~~=== Swimming Speed ===~~
	Maximum swimming Fspeed is 28 and falls to 26 before the next A press. Optimal swimming is on a 20 frame cycle; there are 13 frames where pressing A will be too early and do nothing, then 7 frames where pressing A will result in maximum speed, and beyond that pressing A will result in slower swimming speed. Regardless of when the A button is pressed in the 7 frame window, this 20 frame cycle will repeat.

	=== Straight Lines ===		=== Straight Lines ===
	It should not be surprising that between two points in the water with no obstacles or collision nearby, the fastest path between them will be approximately a straight line. Turning should thus be generally kept to individual segments separated by straight lines, unless forced by surrounding geometry and obstacles. For example, intervening whirlpools and other water currents can make moving in a straight line extremely undesirable, as Mario begins to either strain harder and harder to maintain such a line or gets pulled far off course from it.

	=== Floor Alignment ===		=== Floor Alignment ===
	In ''most'' swimming actions (but not all - water punch/throw are notable exceptions), hitting a floor will cap Mario's pitch from below at the end of the frame, making him parallel to the ground if he was facing into it before. This can be annoying if a downwards angle is desired, but can also be used to very rapidly switch to upwards swimming. It is still possible to swim at an effective angle of up to 256 or 512 into the floor in these states, since Mario's joystick influence on pitch and subsequent actual movement occur earlier in the frame. Importantly, the fact that B swimming and water throws avoid this phenomenon means that B swimming can utilize sloped floors for efficient simultaneous horizontal and vertical movement, potentially avoiding the need to pitch upwards at all. ~~When very steep slopes are available~~, ~~it may even be preferable to B swim into them instead of A swimming~~ up ~~the normal way. If~~ A swimming ~~manages to travel~~ less than 16 units horizontally ~~up a slope~~, then B swimming up it may be preferable. Extremely tall and steep slopes may even make going out of the way to B swim up them desirable. ~~It is also worth noting that if Mario hits a wall~~		In ''most'' swimming actions (but not all - water punch/throw are notable exceptions), hitting a floor will cap Mario's pitch from below at the end of the frame, making him parallel to the ground if he was facing into it before.

	=== Neutral/Opposite Target Yaw ===		=== Neutral/Opposite Target Yaw ===
	The absolute value of Mario's yaw velocity can only ever increase by 16 per frame. However, it can ''decrease'' (return to 0) at different rates. If Mario's desired target yaw velocity has the same sign as his current yaw velocity, it will change by 32 per frame. However, by holding neutral or in the opposite direction on the horizontal axis from Mario's current turning direction, it will change by 64 per frame. Interestingly, this means the input on the joystick's X axis for this in TAS Input will have the ''same'' sign ~~or 0~~ as Mario's yaw velocity.

	=== Ceiling Downwarps ===		=== Ceiling Downwarps ===
	While swimming, ceilings naturally downwarp Mario to their height if he tries to enter them (so long as doing so would not put him under the floor), which can be exploited to travel large distances downwards instantly for free. This can allow more of Mario's speed budget to be put into horizontal movement, allowing Mario to cover not only more vertical distance in a given time, but more horizontal distance as well.
