Four volunteers have spent 378 days living in a 1,700-square-foot space

participated in so-called Marswalks and faced stressors that actual
space travelers to Mars could experience, including 22-minute
communication delays with Earth."

Four people in 1700 square feet for over a year? (If it was a SF story,
at least two of them would have gone mad or been killed.)
What about water? Gravity?

There have been previous exercises.

 Thank you.

 Wow. 6 people in a smaller area.

 Similar. 6 people but a period of 520 days.

 Not a simulation. 1 person with a 4 person spaceship to himself for a
fairly short time.
 

"All models are wrong, but some are useful." - George Box
Generally: it is often impossible and/or unreasonable to do an identical simulation, model, practice run, etc. That does not mean these things will not yield insightful results or info. (It does not mean they will, either.)
I haven't looked into any details about the above-mentioned stuff, so I have no idea what valuable info can be gleaned (if any); but I'd want to know more before rejecting them out of hand.
