HOG 4 Fullsize Screen Pallettes/Sizes

Hi,
I'm programming a show which is going to transferred to a Hog 4 Full Size on Hog 4 PC + Programming wing.
I am trying to program my views so they will be correct/or close enough to correct when I open the show on a Full Size 4.
Can anyone tell me how many scenes I would get across (left>right) if I had a scene view on the entire right touchscreen,
this is presuming I had not unlocked or changed the default size and it was maximised to the largest size.
Make sense? I'm trying to program comment macros that interact with scenes so helpful to know now rather than having to edit macros.
I'm guessing scenes
1>20 are line one
21-30 are line two

Thanks Cormac
