I find the biggest factor in getting a good amount of gpw is to utilize the light as much as you can.
If you got a light meter it might help a lot.
Sometimes no matter how/where you place your lights, there's always a bit of area where the light is cast and its unused (all depends on your room size too I guess).
I hit pretty close to 1gpw with HPS but i know i can reach there if i use a lot of smaller plants to fill the non-utilized light gaps.
