> Although [touch typing] refers to typing without using the sense of sight to find the keys ... the term is often used to refer to a specific form of touch typing that involves placing the eight fingers in a horizontal row along the middle of the keyboard (the home row) and having them reach for specific other keys.

I think they're referring to the latter.

With such a strict definition the OP’s comment becomes basically meaningless. They could be referring to using index fingers only. They could be using an alternative keyboard layout. They could mostly be using left-hand only. Pretty much any WPM between 1 and 200 seems possible with the statement: “I don’t keep my fingers on home row in between key presses.”
