Again, which part of being visibly injured (in the 5th game) during the match are you missing? You are going to lose credibility (not that you care as an ERT fan) if you continue to push these arguments without educating yourself on the details. Harimoto was well on his way to winning before getting injured, after the injury timeout, people asked him to stop playing, but he fought to continue but his best wasn't good enough.
Yes, he has lost a lot of games to lower-ranked players, but he also has won titles and holds achievements that far exceed just about everyone who is his age, even with those losses. Wong Chun Ting beats Lin Yun Ju, no one talks about it. Harimoto loses to Jang Woojin, Harimoto needs to switch to Hurricane. The kid is 20 years old, even with his issues, there is still room for him to get so good at what he does over the next 5 years that he still beats players even with his defects. Remember, he isn't playing in the old ITTF era where you could keep your ranking without playing.
