Distance events and mixed medley added to Tokyo Olympics.

What about Hungary in the mixed medley? If Hungary actually included Hosszu and Cseh in their mixed medley team, they might be minor medal contenders. At both Kazan Worlds and 2016 Euros, they didn't. Instead, they swam a 54.xx male backstroker, a 59.xx female flyer (and one of their 1:01.xx breaststrokers in preference to Daniel Gyurta).
