Just to follow on from the previous thread, from memory I’m pretty sure for the DO they can choose to do their highest scoring dance.
They turn the costumes/styling around in approx 15 minutes between dances on the main show. They’ve got as long as they like to get ready again for the dance off, there’s no schedule to stick to. So while the votes are being counted they get into their ‘highest scoring’ get up. There’s not much else for them to do at that point anyway 🤷♀️
So the clever pros make sure that they absolutely nail one of the dances, as a vote winner and dance-off insurance, and the other one can be a bit rough around the edges.
