The thing is that water weight should be counted into the food items, but at the same time the calculations for that should include how much liquid is in all ingredients combined and then calculate how much of it would be boiled away or in the case of things like pasta be discarded. In the case of pasta the vast majority of the water is not going to end up in your stomache, in things like soup or broth it’s a different story, but still less water than what initially went in there.
I guess my point can be summarised that food items should have different water weight calculations depending on their type they end up as. A solid meal? Only a small amount. A liquid meal? High amount. Dry/dehydrated/preserved? None.
I don’t know what’s up with that tea bug, perhaps to do with the water weight changes, but they should be able to debug the effect away.
I’d also include a point about how the stomache isn’t rigid and frequently stretches to accomodate, but I don’t know if the devs’d be up for implementing that. Up to four liters, more than a gallon. When last have you gone through at entire gallon jug in CDDA in one setting?
