Thanks, SurfNSlide!

I think the only guaranteed items (though not marked as guaranteed) are the engines and AT (When ATs fill the percentage gap). The rest might be random.

They percentages are not the same? I've made the experience that for championships, they are, but not for R&Ds. Unfortunately I didn't keep unopened boxes during this championship. Otherwise I could have seen if they are stored separately in the pending boxes line, like they were during many R&Ds.
