Greetings, the problems it´s about of the product, for example in the assembling machine 1, in velocity is same in legendary in unreal result, legendary vel 2 = unreal vel 2, and mythical is 4.1, my opinion is the next check of result in product in the game : legendary vel 2, unreal vel 3.55 and mythical 4.1 (for example), I hope you will fix of the bug, thanks and have a nice day

Sorry, I don't understand. What do you mean?

My bad, I mean of problems of level in the final of product, in the description of the mod "the level 10 Unreal and the whopping level 24 Mythical", but the level of quality legendary is equal unreal (lvl 10), my sugestion is configure of level unreal is level 15 and mythical is level 21, because i solve the patrons of the increase of quality, for example Quality 1 (basic) = level 0, Quality 2 (uncommon) = level 1, Quality 3 (rare) = level 3, Quality 4 (epic) = level 6, and Quality 5 (legendary) = level 10, is like fibonacci with factorial (n!) in add (lvl + n), sorry for don't understand you. but I hope of resolve the bug of level in quality, Q1=0, Q2=1,Q3=(2+1=3),Q4=(1+2+3=6),Q5=(1+2+3+4=10), is like a some equation, but, in the case Q6 (Unreal) = (1+2+3+4+5=15 lvl) and Q7 Mythical = (1+2+3+4+5+6=21 level), greetings buddy and my bad for write this discussion in english, see you later

The vanilla qualities do not follow fibonacci, the levels are 0, 1, 2, 3, 5, and the general formula is 1 + 0.3·L.

I added the levels 10 and 24 considering the ratios of the increases
Q1 → Q2: 1.3 : 1 = 1.3
Q2 → Q3: 1.6 : 1.3 ≈ 1.231
Q3 → Q4: 1.9 : 1.6 ≈ 1.188
At this point, the qualities are still easy to get but you get diminishing returns

Then we get the higher qualities:
Q4 → Q5: 2.5 : 1.9 ≈ 1.316 (bigger jump than Q1 → Q2)

And the ones this mod adds:
Q5 → Q6: 4.0 : 2.5 = 1.6
Q6 → Q7: 8.2 : 4.0 = 2.05

I wanted to stretch the idea of quality like this to keep the jumps at higher qualities significant, while also keeping Q5 and Q6 relevant even in the late game by keeping Q7 very hard to get.
