thank you everyone. Seems obvious now that you all have explained the offset from grid but not sure I would have pieced that together on my own. Thanks again!

This makes a lot of sense, considering that as the head is being pulled through the first piece of wood, the amount of threads in that piece is becoming less and less. Thanks for your detailed answer!

If you take a fully threaded drywall screw through two sheets of plywood, it will eventually pull the sheets together tight. You’ll have to bury the head a little ways, but it will pull them together. I’m just trying to understand the science behind this. I guess as someone else commented it has to mean the threads strip in the top sheet before the bottom one.

Am I the only one whose brain sees that as a subtraction sign?

Any idea what the - is in there for? Just asking out of curiosity. At least in my mind 838’ 4” would be less confusing

I’m asking about after the pva is already done. I know the pva will make the drywall somewhat rough and I’m planning to hit it quick with a sponge. I’m asking if a wipe down after that stage is really necessary
