My opinion is there can be certain subconscious arch-type handwriting strokes, and perhaps possible scenarios may be offered as to general personality traits.
I have seen examples of paintings where progression of mental illness or brain dysfunction changes how the artist paints and some arch typical strokes begin to emerge on the canvas as time goes by. (Schizophrenia or Alzheimer's for example)
But so many physical things can affect our handwriting.... pain, (even migraine) injury, progressive disease (arthritis or macular degeneration for example) not to mention chemically altered states of consciousness....
it makes me wonder how much those kind of physical conditions would affect the analysis, if they were not revealed to the analyst beforehand.
We have no way of knowing, for example, what Elvis' physical condition was at the moment of writing a note to then President Nixon.
I remember trying on a couple different occasions to sign my own admission papers to a hospital.... once when I was in advanced labor. I couldn't believe how affected my own handwriting was. I wouldn't have recognized my own signature, had I not seen myself write it.
That said, I DID try the test from the site you posted. ..... gotta wait for my email results to see if my personality can be discerned.....
