SORRY PUCK BUT NO ONE EVER SAID DICK WAS NUMBER ONE!! But he is clearly listed as being "second only to Batman" and a "master detective and martial artist" and been trained in all the mentioned combat discplines. No need to mention in skills/abilities about the battles he's lost and won because thats not what an encylopia is supposed to do. 

Also, what your problem is your going by low end showings and not HIGH end showings where he's proven more than a match for a meta like Slade and pinned Shiva down in one of his earliest appearences.
