[Wien] k-points of doped material

[Seyyed Amir Abbas Emami]

​Dear users 

I want to dope in heusler alloy.For this aim i used supercell program but for that doping it was not required to grow cell in any direction and i replace the elements in cell.Now for this job can i reduce the k-points (for non-doping i used 8000 k-points)? If yes how many k-points will be rational? and can i compare the results with the old one?

thanks in advance.
