"It appears that what you refer to as graphologists, in your profession, are much more thorough in their analysis of handwriting and printing than you are. The author of this book makes a point of insisting on original, authenticated standards and doing several different types of measurements. The idea being that when they decide a document's author, it is based on several different tests.
"You did only a letter by letter comparison then. Every letter?"
"A majority of them."
It turned out not to be the case. Diana brought up letter after letter that the analyst had not found a match to. "S" was one of them. Looking hastily through the so-called standards, Avery finally found one, but it was a printed capital "S" which he was saying was a match for a small case scripted "s" found at the end of a word. For all that time and trouble, he discovered it in a signature purported to have been written by Diana twenty years ago! This document also contained the writing of more than one person, and the signature itself was written by Diana's daughter.
Other discrepancies were brought out. T's that were not crossed, small i's with a backward slant, the written letter R which looked like a U. These and other examples of letters found in the 'suspicious' SmurFFs, were not found to be represented in twenty years worth of material allegedly copied from the files.
"It doesn't matter," Avery asserted. "I mean it is entirely possible that the writer could have made an R like that even though I can't show you an example."
"You were given samples of what you were told was my handwriting that covered twenty to thirty years?"
"Yes."
"Is it not true that a person's handwriting may change due to injury or disease such as osteoporosis, rheumatism or arthritis?"
"I would agree that a person's handwriting can change over the years."
