Jones 1245, Reyes 3. Jones 145 is absolutely clear if you even try to assess damage as you're supposed to, and rounds two and three aren't actually difficult to score. And, of course, in retrospect it's pretty easy to tell who did the most damage in the first three rounds by noticing who was more broken in the last two, which is a problem with round-by-round scoring; later rounds really do provide information on what happened in earlier rounds.
Basically, Reyes didn't do anything that counted as progress towards finishing the fight while Jones was doing damage all fight except for in Round 3.
