I mean sure but you can also say that the whole point of this website in the first place is to practice typing. However, the key to being able to type fast is to type the easy quotes first and be start at an easier level. I completely agree on accuracy, I think that it's the most important aspect of typing, but punctuation not so much. When you "practice" easy quotes and get higher speeds it also boosts your confidence and you will be more comfortable with harder quotes after. I feel like if it wasn't for this method of typing for me I would have never imagined getting a speed higher than 100 let alone 160.
