User blog comment:V3hemenc3/What is the accepted number of farm on an AD carry?/@comment-3970297-20120918233317

There really isn't a magic number. You just have to compare your CS and kills to the opposing side of your lane.

Such as if you have 90 CS in ten minutes. [ relatively easy to do.] But your opponent has 100 CS, but you got 2 kills on him and he has zero, you're still ahead of him in gold count. What's important is not really your CS, but how much gold you're getting. While it helps your total gold with a good CS count, you can't say that CS is they best way of getting gold.

Example, Leblanc, who farms champions better than Minions, or Sona who farms assists better than minions, and so on.
