One of these weeks I should work my way up through increasing tape layers and see where it starts behaving; that would provide an interesting data point for where the low end really is...
Isn't there a video on youtube of some guy shaving with an axe? Probably not something you want to do every morning, but clearly this isn't nearly so precise a science as we would like to believe.
