It may be. If they do indeed know more than we do ourselves.
Consider, however, that our records in forums such as these, are permanently stored and searchable by us, our kids, students, and future generations. With correct information this can be an incredible resource, but with information that doesn't comply with reality, it rather becomes an impediment instead.
Forgive my perhaps too abrupt frankness before, but if somebody does research on the Internet ten years from now, and finds this thread somehow, I want them to know that it is in fact possible to make very large prints from a small negative, and that if proper care is applied in the whole process, from exposure to print finishing, they can look quite stunning and be spellbinding too.
