Wilson broke 3 national records but didn’t have all 3 records at the same time. Kendra Stern broke Wilson 500 free the day before the 400 IM. Not to say Wilson can’t break Stern 500 free record in the next 2 years and have 3 national records. It is a rare accomplishment….I wonder how many D-3 swimmer have held 3 national records or more in D-3? That is a good trivia question.
