[phenixbb] dummy atom v.s. model with zero occupancy.

Dear PHENIX users,

In phenix, in order to improve bulk solvent model when the model is not 
complete, you can add dummy atom and set 

My question is that can I just put a model ( I know the approximate 
position for the model) there instead of dummy atoms and set all atoms 
in the model zero occupancy and keep the same setting.

Will I get the same result?   I suspect that model will still be used to 
calculate the Fc even though the occupancy is zero, so the map will be 
severely model biased.
