I do get that 3,840 pph is very high and nearly unprecedented! Higher than Pirates even.
My point was more around how it was possible — and therefore, I don’t think a capacity of even 3,000 pph is out of the question, unlike estimates of only 1,800 pph.
We can effectively look at a “duo” of vehicles as “one” vehicle, if they launch together. So it could be looked at as a 16 passenger vehicle (of which 4 in total are simultaneously loading).
Disneyland’s Pirates is 22 people per boat, averaging a 23 second dispatch from a single stream. This gets 3,400 theoretical pph.
Looking at 16 per vehicle, with 4 “streams”, allows much more buffer time to load.
You mentioned about the ‘leak’ saying that all 64 people will enter the four rooms at once. I agree, if this holds true, it stuffs up my theory.
But I do wonder whether they could lead everyone to wait outside the cell (think Simpsons ride style, with 16 people waiting outside the doors of each room) which then have staggered openings. Then the 16 enter the loading room as the 16 before them hop into the vehicles. A minute later, when that group departs, the current people start to load, as the doors behind open and the room “holds” the next 16 people for a minute.
It really depends on how they do that, though, and the accuracy of the loading style from the leak this far out.
Just an interesting discussion point
