typing speed and the spelling mistakes

I was just wondering about the speed i type the words adn the number of spelling mistakes i do. I just noticed a pattern that almost all the time the mistakes that i do are only when there are 3 letters in the word. Its like saying every 3rd child is chinese, so i named my kid chin-chin-cha.

So i was speaking to one of my friend he confirmed that the typo's happen mainly for the three letter words coz, you would type the 3rd letter faster than the 2nd letter in the 3 letter word. I dont know how far that is true, but i noticed that he was correct and the mistakes i do are majorily in the three letter words ...

anyway, until my next blog :)
