Dancing (calories burnt)

Hi everyone,

I have a quick question about the calorie burning of dancing.
I'm just about to start dancing classes again at Pineapple dance studios in London. The style would be Jazz, musical theatre, street dance etc.
I don't really quite know how to put this down in mfp. Apparantly Zumba burns a crazy amount of calories, while "general dancing" and "ballroom/fast", which are the only real options to choose, burn not even a third of the calories per hour, while I think that my classes, especially including a very intense 20 minute warm up, might be on a similar if not higher level than Zumba.

What are your thoughts? Does anyone know more about the calories burned in a Jazz/Street dancing class per hour?
