I think the point of this question is not "when do the colregs start to apply?", because clearly the rules about keeping a lookout, proceeding at safe speed, showing appropriate lights and shapes etc do apply all the time, whether there is anyone close enough to see them or not.
I presume it is "When do the steering and sailing rules kick in?" -- i.e. if I am likely to be the stand-on vessel in a potential collision situation, at what stage do I have to shoulder that responsibility?

It's a good question - certainly took long enough to get a decent answer. Well said. Unfortunately you haven't answered the question, that is: "is it when the risk of collision exists or is it just before the risk exists?" It's an inprecise question too; as you have already pointed out, there are parts of the Steering and Sailing Rules that apply always, such as Lookout and Safe Speed. If we take the question to mean "when does stand on and give way start?" then the answer is "none of the above". While Lord Esher (and Cockcroft and Lameijer) give us a useful rule of thumb, the given ranges are generalities, not written in stone - I think C and L articulate that fact; for instance a vessel slowly overtaking another could be well within the 6 or 8 mile range for several hours, but it would not be incumbent on the stand-on vessel to hold to a course and speed for that entire time. Instead, where these rules come into effect depends upon the circumstances of each individual case.
