Does anyone know if the judges mark the couples as they would marking pro's, or do they make allowances for the amateurs and mark accordingly? I know Len is the only pro judge, who has experience of ballroom competitions, so don't know what criteria the other three go by.

Have they ever said anything about it in interviews?

Der Chef says

Len sure doesnt

I think his paddles 1-5 have fallen down behind the desk somewhere

Ohhh Yeah

And Bruno's 10 should be taken off him for a while until he calms down
