I can imagine the results changing, even on a daily basis. For instance, if i had to redo the test, today, after being exhausted by two full days of work at hime (gardening, storing woods for winter, etc...), I may answer a bunch of questions differently.
Anyways, this was an interesting reading for me. I don't read much about non physics stuff at the moment!
Have a nice week too! I will be heading to Germany in a few hours.
I wish you a safe journey/stay :)
