I think I might be a visitor from an alien world, because I can move my ring finger when I do your test. But I`m also the kind of person who can type really fast with all 10 fingers, without ever looking at the keyboard. I`m pretty handy with a number keypad too, without ever having to look down. I learned typing on a good old-fashioned typewriter in high school. I picked up the number keypad skills from balancing the day`s receipts everyday at my high school job at a hardware store. :)
I have to admit...my typing style sounds very similar to yours...although a lot of the time I don`t need to look down...I do find that my hands will wander enought to have to look down and realign. I will say this though...I type approximately 80 words a minute when I am copying text from a page to the computer....and about 110-120 when I am typing what is in my head. I found a long time ago if I relaxed and allowed my fingers to go where they needed to when they needed to I ended up typing faster and cleaner than when I trie dto THINK about where I was going. Eventually my brain gets confused and that is when I have to look down for a second...but ultimately I can go for a while and really not have any idea where my fingers are going except to look at the screen.
My typing teacher in high school HATED me...would come by and smack the back on my hand with a ruler because I NEVER held my position correctly and was always just typing....mind you I typed faster than anyone in my class this way...but it wasn`t "correct". My feeling has changed on typing....I say...if you can type...and you can increase your speed by practicing and typing more often...then really...does the POSITION matter?
