Going to install drywall for the first time on an interior ceiling in a new garage, sloped ceiling 10°

The dimensions of the ceiling are 4620x8730mm, and I've bought drywall sheets from Byggmax that are 2400x1200mm. I've installed furring strips 28x70 at 370mm centers (messed up, it was supposed to be 300 centers but I think it'll do unless someone advises against it).

The simplest solution I've come up with is to lay the drywall along the short side, perpendicular to the furring strips.

So, each row will have one full sheet (2400mm) + a cut sheet at 2220mm = 4620mm.

To avoid aligning seams, I alternate which one I start with. The problem here is that there's only an 18cm distance between the seams (and I'll have to add an extra row of furring). From what I've read, there should be at least 30cm between the seams, but I thought since it's on a separate furring maybe it's okay? Or should I cut so that there are three sheets per row?

Thanks!
 
It's calm, especially in a garage.
