"In Instance" & "By Expression" difference in Template override

[Mehdi_Sajjadi]

Hi 

I would appreciate if anyone give a clear explanation of "In instance" & " By Expression" difference in template override?

I always running all override by using  " In instance"  and never have used " By expression" . 

as far as I found if I use " In Instance" , that default values in instance will the same value in template.

But about "By Expression" it will be combination of Expression+ Parameter . 

Any help that help me to understand this "By Expression" and " Base Address" ,would be highly regarded. 

Thanks
