This was my math. First of all, Inno, next time drop one zero off of all the numbers for the sake of simplicity. If everything ends in a zero, just divide by 10 and simplify the math!

So you need 5400/10 or 540 points. Each 3-hour manufacture is worth 10/1 = 1 point. So you need to do 540 3-hour runs in 72 hours.

There are 72/3 = 24 possible time slots for 3-hour runs. So you have to complete 540 of them in 24 possible slots. 540/24 = 22.5 (rounded up to 23, since you can't have half a manufactory -- and no, human marble and elven marble and planks don't count as half, although they should!). In theory if you had a production already finished there would be 25 3-hour slots, but it's more likely that people missed the start than had overhang.

Of course if you use spells you could reduce this number a little bit, but given that you also probably will miss the timing of pickups and might want to sleep, I don't think it's probable that anyone could accomplish this challenge with less than 25 factories running pretty much the whole time. I thought about trying to do it with 27, but decided on 30 to be safe, and then ended up being able to pop in a couple extra.
