When I get the impression I get to low with my highest treble side, I tune beatless over three or even four!! octaves. I check if it is beatless in the upper octave, and it mostly is. So what is all this talk about stretching. I blame the fysicist who published the results of his research saying that the frequency of a upper partial is more than twice, three times etc. You cannot hear that. Because it is all in the system incorporated. You don't need to stretch to make it fit. When it fits it is stretched. You cannot hear it. So actually I blame all the followers of fashion. On the other hand: you can make a deliberate choice to do so because then you have something to talk about. Some musicians want you to do it, but I never came across one who said that my treble side was to low. So I never needed to do so. And again in my opinion I don't strech the treble side. In the bass it is of some importance to my opinion. Because I experience mean sounding intervals as a result of clean octaves. I.e. the quint (fifth) and the 5+8. When I stretch to much in the bass I get dirty 10th's. So how can I match this with your question?? I prefer in the contrabas very beatless octaves, because this is often the way they are played. And above all I don't want for example F'-a to be more fast than F-a. It spoiles the feeling of the root of a chord. But attention: my last check is A''-a, Bb''-Bb etc. And Most of the time I don't hear beats. So I only have focused on stretching, but not really doing it (I mean upon above the natural stretch that you can't hear.) What puzzles me is that I have the impression that the octave plus quint gets oversized in the lower bass, without beats in the octaves.
