I think you were watching a different fight.
I think we watched the same fight, but you gave a fighter rounds simply for moving forward while I didn't. I also considered what each fighter was doing, rather than focusing most of my analysis on how one fighter sometimes missed, even though the other did likewise.
Touching an opponent instead of landing a clean shot, or hitting the cloves, arms, a low punch or when told to break isnt point scoring.
Scoring is based on what the two fighters do relative to one another, and while neither consistently threw or landed eye-catching shots, Rigo was landing more frequently than Donaire was, and Donaire wasn't landing higher quality shots that would make up for his lack of connects. Sure, Rigo landed on arms and gloves, but so did Donaire.
Your reasoning as to what Donaire was doing to win rounds (rather than what Rigo was doing or not doing) was that he landed clean body shots and was the aggressor. But although Donaire moved forward while Rigo moved back, the former was generally less active than the latter and he was less active overall (396-352 for Rigo; Rigo threw more in 8 rounds, Donaire in 3 rounds, 1 round even), so you're giving Donaire points for moving in a certain direction; what is so significant about moving forward that it alone deserves to be favorably and significantly weighted in scoring?
As for Donaire's clean body punches, when did this and his other clean work occur ( in Youtube time)? Rigo moved consistently and Donaire had a very difficult time tracking him down and setting his feet to throw, and Rigo's defensive ability prevented most of Donaires' shots from landing, let alone landing cleanly. While Donaire occasionally landed decent shots, Rigo was more accurate and landed more of such shots, which isn't surprising given Donaire's reliance on being set to punch effectively and his relative lack of defensive ability and speed.
The rounds generally followed the pattern of Donaire coming forward doing close to nothing and Rigo moving back doing close to nothing. Donaire, however, came straight to Rigo, giving him opportunities to score quickly off the back foot as he prefers to, while Rigo's constant and quick movement prevented Donaire from setting his feet, loading up, and scoring with power shots as he prefers to. Donaire fought in a way that suited Rigo (at one point Donaire becomes frustrated and takes the back foot to try to stop Rigo's movement), and he was outscored accordingly, even if he was generally moving forward and even if neither man did much.
Maybe you should watch the fight again as i did
I re-watched the fight and had the same score as I first did. My attention was focused on the fight when I first watched it, so I don't understand why I'd get a significantly different card a day latter as you did.
