Unrelated, The mod uses basic distance calculation to take into account different levels of calculation, so the further away you are, the less is calculated.
evaporated/vapor methanol only exist inside one updateframe there is no calculation outside(gameworld)
The Temperature gain is assumed constant yes it starts to rise faster because if the Still is empty it doesnt get a "cooling" effect from the evaporated liquids(water/ethanol/methanol). This effect kicks in precisely at the appropriate boiling points to mimic real-life behavior.
In fact given that the destillation in the game is an accelereted progress the copper still would superheat much faster with the given energy intake because of the much lower Specific heat capacity of copper compared to water.
Decoupled heating mechanics does have the advantage that you can distill unequal amounts at the same speed and heating. 1.5L kilju and 30 L is the same. Transferrates at the boiling points are in fact equal in the mod.
If this wouldnt be the case it would be near imposible to destill a 1.5L batch. Because the Heating input(which is constant depending on Logs used) would be balanced around heating 30L.
If you cook water on the oven and "vanish" the water will it reset the temperature? Like explained above the copper would in fact superheat much faster if this would be more realisic therefore the mod is underperforming the temp increase.

It Needs To Remove All The Old Datas."
And it does set all liquids to 0 like you would expect when you empty out.
Currently there is no temperature interaction at all with the liquids. Its independed because of reasons given above. I could add a cooling/equalising effect when you add new liquid to it. I also could add that if the still is superhot you get killed because you added methanol/ethanol to a hot still and the flashboiling would make you suffer.
And currently, the firewood mechanics mimic the heating values of a stove. This is not unrealistic, because we have power plants and they know exactly how much mass has to be burned to obtain a certain amount of energy.
