Yeah I was curious about the scoring system as well. And so:
The 10-point Must System is the most widely used scoring system since the mid-twentieth century. It is so named because a judge "must" award ten points to at least one fighter each round (before deductions for fouls). Most rounds are scored 10–9, with 10 points for the fighter who won the round, and 9 points for the fighter the judge believes lost the round. If a round is judged to be even, it is scored 10-10. For each knockdown in a round, the judge deducts an additional point from the fighter knocked down, resulting in a 10–8 score if there is one knockdown or a 10–7 score if there are two knockdowns. If the referee instructs the judges to deduct a point for a foul, this deduction is applied after the preliminary computation. So, if a fighter wins a round, but is penalized for a foul, the score changes from 10–9 to 9-9. If that same fighter scored a knockdown in the round, the score would change from 10–8 in his favor to 9–8. While uncommon, if a fighter completely dominates a round but does not score a knockdown, a judge can still score that round 10–8.
As far as UFC ... I just think that all the grappling/holds type stuff is boring as hell to watch. I totally understand that it is very difficult, very technical, takes lots of skill, etc.
So I'd rather watch Kickboxing, if leg attacks are allowed. But then you get to the simple truth that: legs are much heavier than arms, much harder to control than arms, and are much slower (usually). Unless it's in the lower weights, which I can see is maybe why kickboxing is so popular in countries like Thailand.
But yeah, anyway ... with kicks, I feel like they mostly just miss, get blocked, or are used to slap to hit the other guy's legs, in the same sense as a body shot in boxing. Not really meant to win the fight, just hoping the accumulated pain/damage slows him down later on.
Thus, at the end of the, I agree that boxing is still usually the most entertaining form of one-on-one combat sports.
