my spacing was 24'' centers on the beams so 24'' steel was used with extra long screws 2 1/2 vs 1 1/2 code and up sized also the thickness
I like the steel for being stronger then alloy and 5v for being able to unscrew a sheet to get at a leak in the future but staggered ply sheets should not leak anyway as I have an effective one piece roof with no plywood gaps
all plastic ''tar paper'' replacements ice and water peal&stick for metal roofing was used on top of the plywood with a nailed to code plastic under layer [fought that hard but had to use nails
no local roofer would bid my job my way
so I hired neighbors with some roofing exp to do it my way
the idea was cat 5 proof roof not local standard that is 120mph
I wanted 200mph proof roof and think the laps on the peak and the bent down out side edges
go a long way to stay put with out the danger of flapping and coming off in extra high winds
and for the cherry on top 5 SS 1/2'' cables rated 22k working load strap the whole roof to the concrete ground slab
over done YES but that is how to keep a roof in a cat 5
watched the home next door being built now
one layer of tar paper no tar or cap sheet then nailed on shingles over one layer of plywood
I guess a 100mph wind will destroy that roof
and they sold it for 394k for 1800 sf no garage nuts ?

Nota......I think you won the Internet today with all that....wowie!
That said - it's impressive you put that much into it.
My roof is finished and I will post some pics a little later.
