Also, cheese wheel has -70 hunger change, and cheese has -15, or a total of -120 hunger change...
I did a bit more research...
Vanilla Ice Cream (0.2 weight) equals approx. 700g ice cream IRL, if you compare the nutrition values.
Vanilla Cheese (0.2 weight) equals approx. 30g cheese IRL.
700g ice cream with 0.6-0.8 g/cm³ density equals 1 liter of ice cream. That will give -30 hunger change.
30g cheese with 0.5 g/cm³ density equals 60 ml of cheese. That will give -15 hunger change.
So in vanilla PZ, Cheese will saturate hunger about 8 times as much as Ice Cream, considering how much volume you eat.
You could argue that this discrepancy is caused by the fact that ice cream melts, and fluids dont saturate your hunger as much as solid food.
But still, I think that hunger saturation in vanilla PZ is not that well balanced...
However, 8x Cheese (30g) would mean a Cheese Wheel weighs about 240g (about 2 and a half bars of chocolate). And I think an average cheese wheel is heavier than that...
Especially if you take into account that 4300 calories equal about 1.2 kg of cheese.
So my suggestion would be to increase the number of pieces of Cheese you get from the recipe 'Cut Cheese Wheel', and maybe reduce the calories of a Cheese Wheel a bit.
After all, 4300 calories of cheese from 100-200 calories of cow food seems a bit much.
One possible compromise:
Cheese Wheel 3000 calories, -300 hunger
cut into 24 pieces of Cheese (2712 calories, -360 hunger)
