But, here's the part that's interesting:
""I don't have a least favorite, but when we did the staff tournament, Bronzong was very sneaky. He has some interesting moves, so if you have him it's good, but if your opponent has him it makes it very difficult."
Okay, so that probably isn't the whole story, but at some point they did realize that 70 accuracy was too much with all the excellent Pokémon that could get it and changed it back in the middle of a generation. Notice how Bronzong, along with everything else that had Hypnosis, lost a lot of steam when Platinum came out?
This also endorses my theory according to which they thought highly enough of Bronzong that they felt it was justified to give Bronzors to Byron, Mars and Jupiter.
