They only matter to support arguments in very very close fights, but even in those fights they don't tell the whole story - but people use them as such. Round 1 of Cruz/Cody was close (very close to some) and I thought Dom landed some good heat back. Imagine, for a moment, that we're just arguing about who won that round, there are some (and it happens every fight that someone thinks is a robbery) that would argue that Dom won that "close" round because he outlanded his opponent. Some people have used the stats to argue that because one guy landed more effeciently, that's enough to support an argument that they won a fight or round. And if you give Dom round 1, that turns this fight into a draw.
I know this is an extreme example (and intentionally silly), and nobody would ever think that this fight was not Cody's victory.
