Question of Loyalty

I was inspired by Sandy Holt's thread and decided perhaps my comment is slightly on a tangent so I started a new one here:

In Japan the sense of loyalty is quite deep, but not just in regard to staying at the same training hall but also with knowledge in regards to nutrition, stretching, training.. and the top sensei is to be regarded as the all-knowledgeable one. I've been in this country for quite a long time now so I'd like to ask and confirm what it's like on *the outside*, would you consider it disloyal if someone followed their own personal regimen instead of the sensei's? Is it disloyal not to rely on them heavily for advice for nursing injuries, eating, stretching, etc but rather do your own research on the internet through forums such as these?
