It needs repotting - do it now, or wait?

[K-Sci]

Most of my orchid growing practices, what I consider the basics, were learned decades ago. I think it is reasonable to say that I got most of my general orchid growing practices from Rebecca Northern's 3rd edition of Home Orchid Growing (Van Nostrand Reinhold, 1970). It was the only resource I had for quite some time. One of my hard and fast rules concerns when not to repot.

I won't repot when an orchid is not in active root growth, and I'm very reluctant to repot when the orchid is not putting out a flush, or root growth is at least very active. A second rule I follow without exception is that I won't repot an orchid that may rest during the winter during or just before the rest. For many of my orchids that is right about now.

If an orchid's media is badly broken down I'd rather water lightly to dampen rather than wet the media keeping it on the dry side, but moistening it more often.

Are my rules about not repotting anachronistic or excessively rigid?
