So four people for 200 days subsisting on flour mixing with grounded worm, supplemented by strawberries and vegetables they grew and "a small amount of pre-stored pork and chicken"? Why not just bring 200 days worth of C-Ration? That would be much less energy-intensive and more pleasant than nothing but fried bread, steam bun and dumplings.
No one can survive by growing vegetable on 150 square meters of land and practicing yoga. Definitely they cannot produce the amount of flour which they consumed. So what is the point of this experiment, other than testing the limit of human endurance?
The point is testing closed life support systems, not human endurance. This includes O2 and water.
