All right, what we have here is a virtuoso double-bassist who says he will use 1-2-4, 1-3-4, and in higher positions 1-2-3-4 depending on what works best at the moment. Certainly in lower positions, using four fingers (and I think he does demonstrate using all four fingers in a chromatic run), requires some mini-shifts, just as using all four fingers in lower positions on electric bass would (though I'd call them micro shifts on electric and mini shifts on DB). And if one has the kind of playing experience he does, you're not going to lose the position or start playing out of tune from shifting the hand around.
But what I was saying is that for DB-primary players of more modest skill, mostly we go 1-2-4 or (less commonly)1-3-4 up to the neck heel on DB; and that in the lower positions on EB, that same fingering allows you to avoid the constant micro-shifts required in laying OFPF.
For EB-primary players, I expect (I can't speak from experience, I am NOT one) OFPF is the way to go in almost all positions, unless the scale length is just TOO much for some small-handed players.
In my case, using the same fingerings on EB and DB is suboptimal on EB, I know this, but I do it anyway because I don't have the time to commit to learning EB as a whole new and different instrument. If I became a virtuoso double-bassist, I am positive that I would find places where deviating from 1-2-4 even in lower positions would be helpful for certain passages. Certainly for me at this point in my life, and for many others, allowing the LH to flex all over the place is a risk of losing hand position and playing out of tune a lot.
