Over 200 wpm is indeed possible, however less than 10 people have achieved that. Verified people are Sean Wrona, Alpha_Panda, and Barbara Blackburn, the person who holds the current world record of the world's fastest typist at 215 wpm.
This site and Nitrotype are sites that seem to be anti-200. IF you do over 200, you get banned on Nitrotype. So, we have racers that intentionally max out at 199.
There are multiple people that can do that in the esport network. In fact, we had to set the bar for "Legendary" at 210, because so many people can do 200. On Typeracer, people can post scores well over 200 based off of a short quote, and I've done it myself many times.
In fact, if you watch our stream of the event, you will see quite a few 200+ scores posted. Some races were so close with both racers in 190s/200, and the winner would have to be determined by review (for lag).
