> 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.”
The strict definition of touch typing reminds me of how when I was a kid, my parents would always tell me that there’s a specific way of holding chopsticks. You gotta hold the top one like a pencil, and rest the bottom one between the crook of your fingers and your ring finger, and make sure they’re the same length and the bottom one isn’t moving and you’re just using it as a base to press against.
And then I became an adult and visited China and met actual Chinese immigrants and married a native chopstick holder. And half of them don’t hold chopsticks “the real way”. Somehow it all works out. As long as you can eat a peanut with them, you pass.
As an adult I learned that there’s also a whole lot of prescriptive bullshit that basically nobody pays attention to. The strict definition of touch typing seems like one of those. If you can type without looking at the keys, you can touch type.
