Combining liquids/powders results in overall lower QL

Postby g1real » Wed Sep 09, 2015 4:42 am

I guess this is due to rounding, so there's a debate whether it's really a bug or just a quirk of the mechanics, but still.

Should end up being 15/20/22

I do not understand the screenshot. Which piles are you merging, and what are you dissatisfied with?

I mixed all 3 piles with each other until I got an uniform quality.

And this is a problem?

Pretty sure haven has always flat rounded qualities down. This means mixing anything will always keep them a perfect average or lower them.

How does it determine when to lower the Q, I have been trying to combine my extra seeds and honey but they always go down in Q.

For example to test it I just combined some seeds with the same vit and sub but 9 and 13 ess. Should that not yield 11 ess seed? It turned to 10.

I have the same problem with my honey, when I combine it into a barrel the Q plummets.

same thing happens with seeds in a bucket sadly. You throw in 200 separate 12-13q avg q seeds into a bucket and you end up with 200 11q avg seeds or lower. Wonder if this is why honey q lowers so much if you let it build up because its constantly rounding down.

Assuming that the averaging here is both rounding down at any point and weighted in favor of the larger pile, then its the same problem you had with food troughs in W2.

viewtopic.php?p=51835#p51835

Tl;dr- Any lesser quality added to the pile will lower average quality by at least one, but the real problem is that to raise the quality by just one point, you'd need to add something with quality greater than the pile's quality plus the quantity of the pile. It would make stacking something to avoid entirely.

I can't say its definitely the same situation, or if the underlying math is even similar.

no, it doesn't just take the average of each. Since the overall quality is the root mean square*, I think that is getting averaged together and then the different quality aspects are calculated from that. I'd have to recreate the math, and probably screw it up. It's like an A -> B -> C -> B -> A process.**

*sqrt ( (A^2 + B^2 + C^2) / 3)

**I'm pulling this from the math process used to calculate the purities in Salem. I could be completely off here, but it's what it looks like.

I think it's just a Math.floor() per quality, I can see how it could be abused, but why not just have decimals.

Edit: Okay, I guess storage miiiiight be an issue there.
