That was a wonderful explanation. Similar thought processes although I used ID (with possibly eons of knowledge, experience, and experimentation) to describe what you called the speed of plot.
I point out that the Zerg Psionics are connected to/enhanced by the Void...which is like the Multiversal Warp.
Its limited numbers and expansion capacity would be mostly explained by the fact Amon wanted to win in the end and if the Overmind could keep producing Cerebrates or evolving itself to be able to handle the load, it would be unlikely it would be killed, since it could hide thousands of lightyears away from the Protoss with the intervening space filled with Zerg and a far larger invasion force attacking the Protoss. At this point, the Overmind would likely be far to strong to input more directives as well, and thus Amon would lose and the Infinite Cycle would continue...based on his motives and dialogue, I am not sure he could even stomach that thought.
This will likely be my last comment on it. If you hadn't had such a wonderful post, I likely would have stopped as it was.
Makes some sense.
Limits placed on the Overmind by Amon or his followers is one handy way to explain the strange shortcomings of the Swarm.
For example, given that the Overmind knew even more about Khaydarin crystals than the Protoss and could apparently use them,
why hadn't the Swarm already integrated Khaydarin crystals with its biotech even before the invasion of Aiur?
Wasn't that more because they were just taking their time evolving Banelings from scratch? It was shown at the end, that they had the capacity to take it out at any time after all.
Back to point, I am unsure if Blizzard has ever given us direct numbers...whenever we get the "space bugs" motif, it is rare for the number crunching to be added.
Sort of.
Remember that they were trying to turn a mold that causes tooth decay when eaten too much into
an explosive capable of wrecking the bridge of a capital ship.
It's not a simple case of assimilating an organism to get its useful trait.

As for the topic for which you were replying to Generica (which I had missed because I was simply trying to reach the latest chapter back then and ignoring the discussions on the way
),
i.e. how fast do Zerg reproduce:
there's the
long term sustainable rate and the
short term rate.
For the long term sustainable rate:
In the short story Broken Wide (where the baneling evolution example comes from),
one hive sent a new wave of "hundreds" of prototype banelings
every day against the Terran base. And this went on for several months.
From there we can roughly infer that, at this one hive,
either hundreds of larvae were morphed together into new Zerg within each day,
or a larva was produced and morphed into a new Zerg every, say, 24/200 of an hour or faster,
or something in between.
This is probably constrained more by how fast the hive was obtaining and processing resources rather than the potential growth speed of the Zerg, due to my next example:
For the short term rate:
In the short story Just an Overlord, the titular overlord led an attack on a squad of marines near the top of a building.
Some of the marines tried to escape by taking the elevator downstairs.
Noticing this, the overlord immediately ordered some larvae in its hatchery to morph into new zerglings, hydralisks and roaches, who then tunnelled into the building
in time to intercept the fleeing marines shortly after the latter exited the elevator.
In this case,
the game mechanics seem to be canon. (assuming a real-life range for how fast the elevator ride was)
This does not contradict the previous example because, it's one thing to spawn a new squad RTS style, it's another to keep doing that
every day for almost a year using just one facility and not run into resource issues.
As for how fast a hatchery can be grown without creep,
in Just An Overlord, it took about two days for the overlord to find a drone, morph it into a hatchery, spawn a flock of mutalisks and banelings, and start attacking the marines.
We can take that as the absolute upper limit for how long it takes a hatchery to be grown, but it's unlikely to have really taken that long, especially considering the following example:
In the Ghost Academy manga series, there's a scene of a drone morphing into a hatchery, which has sound effect words implying that the drone practically
balloons into a hatchery in
real time. (i.e., once again, game mechanics seeming roughly canon)
Of course, it's possible that the time taken does vary depending on how fast the drone can absorb the necessary raw materials to use for its transformation.
e.g., on very "good" ground, with the optimal combination of "nutrients", it could grow into hatchery within minutes, but on an inert, barren ground (e.g. the surface of a space platform), the transformation might indeed take more than a day.
As for the case when there's
already a vast supply of Zerg biomass to use (e.g. a plain of creep), there's no doubt that a Zerg structure can be grown in real time.
In the short story Cold Symmetry, the Protoss zealot protagonist saw a spire growing right in front of his eyes.
but the best example is the nydus worm. It extends forward by
growing forward, and one need only look at the Kerrigan vs Narud fight cinematic in Heart of the Swarm to know just
how fast a nydus worm can extend.
And how fast does creep itself grow ?
In the novel StarCraft: Uprising, it's remarked that a little tub of creep expanded to cover the entire interior of a room "in minutes".
On a larger scale, it can be estimated, from novel descriptions and the SC1 campaign, that it took the Zerg about 18 days to go from no noticeable presence on Mar Sara, to covering most of the planet in creep.
Anyways, in crossover fanfics, one can always significantly tone down Zerg growth speed and explain that away as being due to, say, the lack of vespene gas.
(or conversely, boost Zerg growth speed due to finding a superior resource)
...
Now you guys may be asking: if Zerg growth rate is that fast, how can the Terrans or Protoss deal with them?
First off, scary as the growth rate may seem, it's not always the decisive factor in war.
e.g. when the Terrans and Protoss decide to glass the planet, there's usually nothing the Zerg can do about it. (unless the Zerg already have space defenses in place)
Secondly, the Terrans and Protoss make up for their slower growth rate with other ways of efficiently reinforcing their armies.
e.g. the Terrans used to "train" new soldiers by grabbing some convicts, putting them into special tanks and reprogramming their brains,
and the Protoss use their teleportation to get troops to wherever they want near-instantaneously.
And while the Terrans and Protoss cannot reproduce biologically as fast as the Zerg, the speed at which they manufacture their robots, vehicles, fighters etc has been implied on more than one occasion to be quite fast as well.
