In this code sample:
public class SuperMan {
    private static bool IsProper(decimal x) {
        return x > 31.0m && x < 45.0m;
    }
    public bool CheckStuff(string a, string b, string c) {
        // lots of code, some of which introduces a variable x
        return IsProper(x) && /* other conditions */;
    }
}
Should IsProper(..) be a 'private static' or a 'private'. Assuming:
- IsProper(..) doesn't need to access any instance state.
