I use multiple RCs. If there is something to read, I read it, look elsewhere, read again. Else I do the nose pinching. Is that good or should I do only one RC and always the same?

The problem is that I never (or don't remember) of having been lucid because I made a RC in a dream, so I don't know which one is not most efficient for me

In addition. Each time before doing a RC, I try too determine if I'm dreaming or not (but then I will RC anyway), by asking myslef "what was I doing before? and before? Should I be here?" I also look at the environement, details, try to change things. Does everybody do the same or am I doing too much?
