Your overall conclusions are sound, but your descriptions of how terrain, path finding, unit orientation and collision boxes work and interact in SC1 is just plain wrong.

Your analysis of how the tiles (or grids, as you call them) of the terrain interact with units is. well, just utterly wrong. Units do not "try to sit on top of a tile" as you claim. All that "bobbing around" of units is just because one collision box gets in the way of another.

And those pictures are just bad and totally improper to explain anything about the structural basics of pathfinding in BW.
Here's another picture, directly from SCMDraft (map editor), displaying the important aspects much better:

green: terrain tiles
grey: sub-tiles (these are the relevant ones for pathing; each tile is made up of 4x4 of them)
red: collision boxes of the units. For ground units (except workers with mining command) these are not allow to overlap under normal circumstances, and if they ever do, resolving that becomes highest priority action for the moving algorithm, before any other action. This is why worker drills can disrupt units from attacking.
greyed out areas: unwalkable sub-tiles, collision boxes of ground units are not allowed to overlap with these under normal circumstances, resolving terrain collision has priority even over resolving unit collision (although it is possible to transition unit collision into terrain collision, as demonstrated in the Blue Storm video).


As you can see from that picture alone, there is no difference at all between Dragoons, Vultures, Goliaths and Siege Tanks. they all have the exact same collision box and thus behave identical as far as pathfinding goes. So why does one need to micro them (and against them) differently? - Because of other differences like:
- unit orientation: vultures always point in a certain direction, to have them ready to fire one must make sure they face the direction of the target. That's why they work best with patrol micro (patrol basically gives them a direction order on top of an attack order), dragoons on the other hand have no orientation, so they are always ready to fire and can be microed by hold position. Tanks are kind of in between, in that they are basically two units in one, one chassis and one turret, each with an orientation of its own. The chassis is facing into the moving direction, but the turret can still rotate freely and stay locked on a target in reach, thus resulting in an overall unit behaviour that is closer to that of the dragoon than the vulture. Goliaths also feature a turret, but a less mobile one that can only rotate a small angle, thus requiring the whole unit to be aimed at a target to attack
- attack animation: A dragoon has to stand still for a while to "cough up" that lightball of his and giving it any new order before the projectile is launched will disrupt the attack, Vultures on the other hand fire instantly, if facing the target, and thus can keep moving constantly. Tanks and Goliaths also pretty much fire instantly.
- unit speed and acceleration: units don't just stop when ordered to do so, but have a short phase of deceleration. This is relevant when using fast firing, fast moving units like vultures, because it means that they can fire while still moving and just keep moving, when given another move command right after the attack (also important for muta and shuttle micro, for example)
- rate of attack: Goliaths pretty much fire one attack after another in rather short succession (not quite like Corsairs, but still...), whereas Vultures, Dragoons and Tanks have really long attack cooldowns, which is why the latter three are much better, or at least easier, to attack-move-micro.
- projectile type: Goliaths (vs. ground) and Tanks do not have projectiles, their shots hit almost instantly. Vultures and Dragoons (or Goliaths vs. air), however, fire projectiles that only apply damage once they hit the target. This means that their attacks can be dodged by "removing" the target, like loading it into a transport or bunker, it also means that they are more prone to land overkills, i.e. fire more projectiles at a target than would be required to kill it (tanks do this too, however, especially in siege mode.).

i think zerglings should be able to jump. not to attack air units but just to be able to jump onto cliffs or over zealot walls or terran wallins and the such. they could also jump from island to island (making 6pool on isles viable) but if they miss they drown.
