I could only remember my son lost perhaps a total of 5 matches (out of more than 800 matches has has played) because of bad calls. But he probably lost a couple of dozens because he played the out balls.
I hear you my 10 year old plays out balls all he time. I think serves are the hardest for him to call. He plays lots of balls that are a foot out.
