How many screws to fix plasterboards?

[Arnold9801]

I have a lot of plasterboards to fix on our new builds stud partition walls upstairs. I've started by using 5x columns of 10 screws on each sheet of 8ft x 4ft plasterboards resulting in 300mm spacings. With 50 screws per sheet my plasterer says the spacings should be 9 inches apart on the walls.

 

Could someone advise me on what's best as British Gypsum says on their website to use 32 drywall screws? I'm using more than they recommend and yet my plasterer says I should be using more than that again!

 

Many thanks.

Every 200 is fine But gypsum actually mark them on with a green x every 300

Add more where you feel it needs it. 

Board joins

slammy door jambs. 

Thin wonky bits.

I think they are referring to the length of the screws:
