Agreed! The test isn't a test unless you limit yourself to the set of gear you are testing. If you are testing skills / gear that are minimalist (PSK only, EDC only etc) then you will want to do somethings to make your experiment a little safer than a true survival situation would be. There are situations that could creep up on you and make you "too stupid to survive". Hypothermia and dehydration come immediately to mind. To mke yourself a little safer you should make this experiment with a partner and watch each other. Don't help each other but watch each other. Make sure that you each have agreed to allow the other to judge your safety. A few cheap monitors of the basics would be good too. Get one of those stick-on thermometers at the drugstore and use clear adhesive tape to tape it to your chest or belly . Check it now and again. If it gets below 95 then your are objectively in trouble! Every now and then try to spit. If you can't spit you are objectively in trouble. These simple tests and others that we could think of may help you to decide when you have reached the limit of your gear / skills and must fall back on your safety net.

Starting the experiment with a long, exhausting run would also be a good thing to help simulate the stress of getting into a survival situation.

Starting at night would also be a good thing since you don't know when this will happen.

If you plan to test your trapping, fishing, hunting skills either go truely remote or get the lisences required.

Don't cheat but do know when to quit. Training to survive doesn't help if you don't survive the training.
