Sue, I think the predictors do have some use but I see too many people rely too heavily on them instead of learning how to better predict their performances through all the clues that many of us just naturally do, which take many of our individual variables into account.
Interesting thought on the mental side of things and I think there is something to that. I think it works both ways. Sometimes, we convince ourselves we are as good as we think we are and we race to our full potential. Other times, we convince ourselves that we are not as good as we really are and we race down to what we think we're capable of. The one issue I have is, especially with Yasso 800s, people often convince themselves they are capable of more than they really are capable of and get themselves in over their heads. Then, when they struggle through the second half to a 20 minute positive split, they get frustrated. Well, using a workout run at 5K race pace to predict marathon potential works if you're equally well trained for both short and long. However, most people are inadequately trained for a marathon so doing such a workout is going to dramatically overpredict their marathon potential.
