A quality increase chance of 12.8% or p=0.128 means:

p(normal+) = p^0
p(uncommon+) = p^1
p(rare+) = p^2
p(epic+) = p^3
p(legendary)=p^4


Upgrade chances are 10% per level regardless of the base quality chance:
p(normal+) = 1
p(uncommon+) = p
p(rare+) = 0.1p
p(epic+) = 0.01p
p(legendary)= 0.001p

This assumes [...] that the exchangers use their full capacity of heat energy before sending it down the line.

They do. As long as they are getting heat at any temperature above 500°, they will work at full speed (or at least, at the speed permitted by the supply of water and required by the ...

So what am I overlooking here?


Three things.


As has already been mentioned, you don't just have the heat capacity of the reactor, but also that of the heat pipes. It may still not be quite enough to store an entire fuel cell's worth of energy, but it will be much closer to that.
Perfection ...

it would be easier to just build some random 2xN without optimization, and still get more energy out of the consumed fuel cells just because of the increased neighbor bonus.


It's not even just about optimising use of fuel cells. The reactors themselves are expensive capital items, and more ...

I wouldn't say it is a "regression". Rather unnecessarily complicated. Because it would work. In the end it would be similar to how we did it before 2.0 when we could not read anything from the reactors yet

Exactly.


temperature getting too low is the simplest way. Usually I set it to 550°C to ...

If so then restricting foundries' LDS recipe to common only don't make any sense.

Indeed. OTOH, quality fluids would make getting quality holmium much easier.

There is a slightly easier way to guarantee that you only ever put one cell in. Set up your reload condition on one inserter set to remove the spent fuel cell from the reactor. Wire a circuit to the inserter, reading hand contents. Wire that to the inserters that put fuel into the reactors. Give ...

Possibly because you are filling the internal power buffer of the radar that was depleted during the night.

I felt there was something off in the wording but i'm not native english and the "Do you ever use(present tense) the sandbox?" feel very unatural to me.

"Do you ever use the sandbox?" is absolutely natural and normal English. It refers to present (or recent past) habit, and asks nothing about ...

The first and third options clash because of the different tenses.

Not even the power boost on Vulcanus can make solar a viable primary power source.


It's not the power boost that's most important (though it certainly helps) but the hugely reduced materials cost. On Nauvis, even ignoring the space requirements, the capital cost is very large. Solar power ...

You obviously use the method that works best. That's why balance is important so that the tradeoffs lead to varied factory designs that are actually competitive.


Indeed. And I think that currently solar and acid neutralisation are well balanced on Vulcanus: if you have spare space, build solar ...

Stargateur wrote: Sun Jun 08, 2025 6:09 pm if you ask me, this way to generate power on vulcanus is broken and unfun.

So just use solar, which is extremely cheap to build on Vulcanus. The only downside is the space requirement (but even that is still much less than on Nauvis).

It takes each combinator 1 tick to process input to output. If you want to make sure that you are comparing results from the train contents at the same instant, your two chains of combinators have to be the same length. If one is a step longer than the other you can insert a 'dummy' step before ...

That's 50% relative boost per cycle, not per successful quality raise, and you average multiple cycles for each level.

when you recycle underground pipes, you'll get both pipes and some iron. You can then make more pipes from that iron (in a assembly plant), which will give you slight boost. The whole question is, whether this boost is enough to get pass the problem with the double recycling. Because if you get a ...

Recent posts about quality has reminded me of a problem I observed in quality production: if you afk for long enough and leave an upcycler running, there will be a significant bias in leftover products that strongly suggests the recycler output distribution being biased.
