Yes, the choreographic lift got a definition, BV and points this season.
As to why D&W seem to do better earlier in the year than V&M, I think there are several contributing factors:
1. D&W don't have the health issues V&M do. I bet V&M are very careful not to overtrain.
2. Charlie White's music cutting ability lets D&W make changes to their music and programs much faster than V&M. As soon as they want something fixed, they are 3/4 of the way there.
3. It's got to be harder to get a new lift smooth in the transitions when team members are closer to the same size (as per V&M). It takes longer, therefore, and they are not quite as ready quite as soon.
The above I'm fairly sure of. The following is pure speculation.
1. V&M seem to be very vested in having a story even for an SD while D&W are perfectly happy with "Charlie & Meryl go to a party" as a whole story. I don't think Tessa & Scott settle down into a program until they have the acting stuff straight. It takes longer. In the case of this year's SD, they still haven't got a clear story line, and that program just hasn't gelled as well as Carmen. Frankly, any stories I can come up with for their current SD music cuts are just weird. What would explain suddenly breaking into a polka and looking unhappy about it? Why is such a dressed up girl with a guy all in black anyway?
OK-he's a spy. She is caught making up to him. As torture they are forced to dance a polka. They escape and waltz again. (that's my best effort
2. I think they don't get fired up to really work until they lose, or at least have some team finish close to them. I don't know why this should be, but it's one explanation for losing the GPF this year & last.
