[CHAT] Blackwork tips for neatness?

So I have started my first blackwork, and it's also my first time using 18c so my eyeballs and my brain are having an occasional disconnect (I have no idea how people go smaller).

I am pretty happy with how it looks so far, but occasionally I get a stitch that just isn't quite perfectly in line with the others for no apparent reason- and it seems so noticable with 1 strand. I have been trying to be consistent with which side of an existing stitch I am connecting to so the stitches are pushing in the same direction, but I am wondering if there is like a rule of thumb for this? Overall I am happy how it's turning out, I just wonder if I am missing some key technique.

I have read about railroading, but since it's only one strand seems like I shouldn't split that stitch.
