Probably.
After studying the definitions, I was sure I was a 3.5 or higher. Problem with the definitions is that they don’t account for the skill level against who you play. Case in point is regularly returning moderately fast serves. Well, if all you know is playing against newbies, your metric is skewed. I learned that when going to an open play at our community park and could not return super-hot serves dished up by what I later learned were 3.5/4.0 players.
