MyWellness, Fitbit & MFP

I have a question regarding mywellness and fitbit integration.

Firstly does mywellness pass onto mfp any information regarding exercise to mfp? It said on the mywellness site it takes meals information across to mywellness but I have been unable to find out whether it imparts any information in the mywellness->mfp direction.

I also have a fitbit. I havent been very impressed with it overall but I am going to stick at it. Its linked with mywellness but should it also be linked with mfp? I suppose this question gets answered in part by answering the first... dont want to be double dipping from two different links.

Any help would be great.
Thanks!
