-Not enough stitch length will cause a ball on the bottom side and material will stop feeding
-Too wide of a zigzag squeezes the fabric together resulting in loose stitches that will end up balling up and not feeding.
At most, I would go down ,back, and down again, 3 total passes.
Slightly to the side is no big deal and may indicate you've got too many passes already or zig zag too wide and the bar tack is getting tall because it's balling up on top.
It doesn't have to look perfect like embroidery with perfect stitches and no fabric showing to be functional.
