why have you not detailed the critical step of how much space you need between the sheets so we know how to space the rafters? Surely that would have been an obvious thing to cover in the video? If using 700mm wide sheets then how far do the rather need to be spaced apart? 725mm maybe ? I need to know this before installing the rafters?
No. Especially not with a roof structure like they show in the video. Most roof structures with that span would have at least one row of blocking between the rafters. If you were to stand directly on a rafter then you might be ok, but do not stand on the polycarbonate without a solid surface directly under it for support.
Use 12.7 mm or 1/2" wood drill bit to drill holes for the super fixing buttons. How the hell can I get 12.7mm drill bit? In the civilised world people use mm not inches. Easier to get a moon stone than 12.7" drill bit...

With the flashing tape, did you just peel the top half off first and stick that? it looks really tricky.
What should be the spacing of rafters
Can you walk or kneel on the sheets when fitting?

I don't think the size has to be exact.
Use a "half inch" drill, if you cannot convert. Its close enough. ( thats .500 inch )
