Dream Land technical stage info

[ComJay]

Using a stage editor and some screenshot editing I have made this image displaying x/y coordinates for object placements and collision points. Below you can see the respawn point for when KO'd, where each player spawns, where items have a chance of spawning if turned on, where Kirby would appear during the game's intro, and all the collision.
I also have this image of the blast zones surrounding the collision, but since it is too large to embed here, I'll just leave this link.
(EDIT: Y position of the middle platform is supposed to be 1542. I made a typo for the left side.)

The interesting things here seem to be that:
-the right plat is 3 higher than the left plat and extends 51 further towards the ledge
-the top plat is 30 taller on its left than on its right

Can anyone think of ways where these may matter? I have always subconsciously preferred the right side, but I don't think this has anything to do with it.
A list of jump heights would be cool. I will make one if it doesn't already exist.
