While it would've been better for Strym to actually link the scan alongside the profile rather than just the profile which has the scan in question within it, it doesn't mean he's incorrect or wrong for linking only just the profile.
Especially since the scan in question is in bright blue hyperlinked coloring on their speed category, which is extremely visible for anyone to see, if i, someone who isn't knowledgeable at all on Pokemon can clearly see the scan he's referencing, than someone like yourself who is knowledgeable about the verse would also be able to see the scan just as, if not better than me as well.
Hell even Strym basically
re-stated what was the justification for
Giratina's speed in that exact same thread.
