I am trying to listen to FM station using an SDR and GNU radio. I have followed this procedure [![enter image description here](https://i.stack.imgur.com/yTKYW.png)](https://i.stack.imgur.com/yTKYW.png)

Is there a reason that the decimation is done gradually? For example would it make a difference if I change audio decimation to 1 in WBFM Receive and change the decimation to 50 in rational resampler block?
