The brewing stand emits a dumb signal (comparator) in relation to the fuel and ingredient.

First, I ask that you at least pay attention to the problem in any case, and I apologize if this report doesn't fit the description, as it's clearly a bug, but one that, due to lack of attention, has become a "normal game mechanic" over time from what everything indicates.

In simple logic, each bottle in the holder increases the signal strength by +3, and the fuel and ingredient slots should increase the signal strength according to the quantity of their respective items, being +1 signal strength if there is at least 1 item in the slot, and +2 signal strength according to a percentage of the total quantity (probably 1/3 and 2/3 of items in the slot respectively).

Currently, according to the documentation, it follows a completely strange rule, which varies both according to the number of bottles in the holder and the amount of fuel and ingredients that are counted together.

Due to this "clustering bug" in the fuel and ingredient count at the brewing stand, any automated farm project becomes unfeasible in survival mode. In fact, most (if not all) farms found are semi-automatic, requiring you to wait for production to finish before manually restarting the process, as it's not possible to easily verify if the process has been completed and thus drain the brewing potions into hoppers to then restart the process.
