User blog comment:CrashBash/Random Musings 3 - Extreme 1, before or after Series 5?/@comment-24393094-20170813200406/@comment-2118191-20170813201628

Well, Behemoth vs The Spider was certainly filmed after Series 5, and we have official word that Dominator 2 vs The Executioner was likewise. The other three are a little vague, but honestly, it seems like it'd make sense for them to be after, and besides, the lighting for the arena is also more Series 5 than the original Extreme 1 block.

Sometimes, the devil is in the very fine details.
