A person can be wonderful, "Christlike", humble, loving, a genuinely good person, but be below 10 hours, and you are not "exemplary",
A person can be a borderline prick, or even a full blown prick, and if they are consistent with 10 hours or more, or worse yet, actually pioneering, then the sky is the limit for them.
Why do they almost only interview "full time" servants instead of "Christlike" servants at the Assemblies? There it is in a nutshell, its about your time, not your attitude.
Is it dangerous? Yup, esp for those who prefer to be a good person instead of a good producer.
