I'm glad to see wiser heads than mine jump in on this.
Bart makes some excellent points. As one just recently emerged from noobdom, I'll agree that the meme of "no pressure" is everywhere. To this day, I'm convinced I've not yet overcome or fully grasped all the nuances.
But I do think that it breaks down like this: there are two types of people in this word. There are the types of people who understand intrinsically how the world works on a physical, tool-user level, the group of people who are good at working with their hands. The other type of people understand and manipulate the world in a different way. Think of it in simlistic terms, if you will, as the difference between operations and management. Not to say or imply that one is exclusivley better or worse than the other, or that each group doesn't have any overlap, or that being a member of one excludes the other. But it's been my experience that you can give a member of the former group a physical task to perform, and, with a bit of intial familiarization, will often be amazed at the progress that can be made. The other group, OTOH, is "all thumbs". Some people have a feel for doing stuff. Some people don't. If you have to give advice to both groups, IMHO, you've got to keep it relatively simple. Basic enough that the most extreme example of the second group can understand, and succeed with. The first group, OTOH, will quickly leave most basic instructions behind, and start to do things with it that break all the rules. If I was hanging out on, say carpenterstuff.com, as confidant as i would be in passing advice on the use of the circular saw, I would never recommend "advanced moves" to a beginner, and I can't help but think that the "no pressure" idea is nothing more than a function of exactly that.
You could apply the same dichotomous division to those who accept "rules" at face value, and those who question them.

But then, I've always been the type of guy who, when the crowd is moving left, i'm dodging to the right.
I've seen one fellow do a TPT that would have, at the very least, resulted in a rolled edge. It was enough to make me cringe to watch him plucking it like a guitar string. In much the same vein, I've grown to believe that the TNT, if performed
appropriatly, can be done in such a way as to minimize any possible damage.
And, for me, I find that there is something further transmitted through my thumbnail that is damped or lost in my thumb pad.
I have done a few rather informal test, testing for HHT before, and again after, the TNT, and i can't see any difference at all in the HT performance Wether it affected the shave, i'd be at a loss to say...
What is it that everyone says? It's all in the hands...?
