However, I don't search for a "breathing" floor, just for a ronda moving in a coherent way so that the phrases of the music can get recognized. But without audio there seems to be a muddle of movements.
I have looked at a few, and there are some that look better to me than others, but i can't quite articulate the difference, so have no evidence that this is not just me being biased because i know the milonga - there is probably always some muddle of movements because people do different interpretations, and i am not sure what makes it feel different when one is inside. (even complete synchrony is probably not a good indicator - i have been on dancefloors dancing one of the milongas with the really obvious breaks, and literally everybody hit them, but it was not a very comfortable ronda)
In some ways it is similar to freeway driving - sometimes it is relaxing kind of school of fish feel, where we all work together and the traffic just flows, and sometimes it feels like a ben hur style race where everybody is out to get everybody, and i am not sure if it looks objectively different.
