I usually get 4:1 panos using 16mm nikon lens with 6 shots and zenith, i dont take nadir as i usually replace the area with my logo

If you want to shoot equirectangular (‘spherical’) panoramas rather than cylinders they MUST be 2:1 width to height ratio. I’m afraid I don’t have the linguistic knowledge to browse your site effectively, I apologise!
