Perhaps it depends a bit on if you are using 9 or 12mm board, I usually
use 12mm and have never noticed any sag at all in the space of 400mm
(i.e 32 screws per 8x4' board).

First time I put PB up I just put one screw in the middle of the sheet,
and said to the guy I was with 'thats alright, innit.' The look on his
face was so funny

Thanks guys.

Off work for the rest for the rest of the week after the bank holiday,
so will hopefully do it then.

Will update as it goes.
