Simply because it can't. No system is perfect, and we have debated of it for litteraly 10 years, from Supremacy 1914 to Conflict of Nations.
The only thing where there is more or less a consensus is that "good stats" or "high score" don't necessarily imply a high skill.
My personal position (as an alliance leader) on stats is that they are interesting insights about how a player plays, and what environnement he is playing through.
Subtle statistical anomalies or a big "delta" from the average of a player may hint on what kind of units he likes to play, or what kind of opponent he is used to encounter.
How much AI vs Player were killed, etc etc etc.
However, it doesn't give a lot of clue about if he is skilled or not. (well, a 0.15 K/D is often explicit, but a 2.5 K/D isn't, especially in CoN where it's the feast of the 10 vs 1 )

Running an online alliance is pretty much like running a small company, except you need to find other way than money to keep your employees productive. May they play or work, they are humans.
