TL;DR
The Tips and Tricks menu explaining quality probabilities should be updated so that quality is not misunderstood.What?
The quality probability tip uses 4 normal tier 3 quality modules, which gives a quality chance of 10%, reflected in the image below. Each subsequent chance for a higher rarity is 10% of the previous one (1%, .1%, .01%), which leads a player to believe that whatever quality chance you have for the machine is rolled again and again for each subsequent level of rarity. In actuality, this only happens the first time; if you have 4 Epic tier 3 modules, reaching a quality of 18.8%, this only determines the likelihood of upgrading to the next tier, while each tier after remains 10% of the previous chance. This should be amended either by explaining this rule of quality more in depth, or by choosing an example in the tips and tricks menu that does not use 4 normal tier 3 quality modules, so that the players can see the 10% quality cap behavior.
