I tend to look at K/D for each round, and then also consider the kit they played with.
I think that to get over the 1.00 K/D ratio, means a player can be classed as good. Dont forget that if you take out being bombed and arty'd you would probably have a K/D of 1.3
Also Bex, I remember my stats looking very bad after my first 50 hours, and that will probably be the same for anybody who hadnt played FPS before.
Some people are naturals, whereas some need to ride the learning curve.
