Right now, however, I am being somewhat thrown off by the way the data is presented. For example, skidding deceleration ... subtracts 0 blocks, 0 pixels, 1 subpixel, 10 subsub-pixels, and 0 subsubsubpixels from the appropriate values?
Where did you even get those numbers? Next to "Skid Deceleration (normal)" I see "0020", which is 2 subpixels (or 0x20 = 32 subsubpixels (or Sonic-style subpixels)).
For a start, it's in hex; as such, each is 16 times smaller than the previous element. So there are 16 pixels to a block, 16 subpixels to a pixel, 16 subsubpixels to a subpixel; this means 256 subsubpixels to a pixel.
In other words, 1 subpixel = 1/16 pixel = 0.0625 pixels; 1 subsubpixel = 1/256 pixel = 0.00390625 pixels. "0020" is therefore 2 subpixels = 0.125 pixels. "0280" is 2 pixels and 8 subpixels, or 0x28 = 40 subpixels. Either way, it's 2.5 pixels.
Here, let me translate the bulk of it into pure pixels:

MIDAIR PHYSICS
If Small, Big, Fiery or Hammer Mario:
- Releasing B and/or Left/Right has no effect on your speed.
- Holding the direction of motion accelerates you at a rate of 0.0546875 px/f^2 (up to 1.5, 2.5, or 3.5 px/f)
- Holding the direction opposite motion decelerates you at a rate of 0.125 px/f^2
If Raccoon or Tanooki Mario and NOT in flight mode,
- Releasing Left/Right decelerates you at a rate of about 0.0625 px/f^2 until you reach a speed of 1.4375 px/f
- Holding the direction of motion accelerates you at a rate of 0.0546875 px/f^2 (up to 1.5 or 2.5 px/f)
- Holding the direction opposite motion decelerates you at a rate of 0.1875 px/f^2
If Raccoon or Tanooki Mario and in flight mode,
- Even when holding B and the direction of flight, you will decelerate at a rate of 0.015625 px/f^2 until you reach a speed of 1.4375 px/f
- Releasing Left/Right decelerates you at a rate of 0.0625 px/f^2 until you reach a speed of 1.4375 px/f
- Holding the direction of motion accelerates you at a rate of 0.0546875 px/f^2 (up to 1.4375 px/f)
- Holding the direction opposite motion decelerates you at a rate of 0.1875 px/f^2

That's not everything, but it's most of it. You should be able to work out how I got the values I did from the ones in the image.
