Pull sufficient yarn into the stitch on right needle is used primarily in JSSBO over a dropped stitch.
I noticed ages ago that when I’m binding off I automatically pull extra yarn into the stitch on the right needle after pulling the stitch over it. This means that my bind off is never too tight. Although pull sufficient yarn is specifically speaking about binding off across a dropped stitch, pulling up extra yarn into the stitch on the right needle is good for any bind off and will keep it from shrinking over the bound off stitches. Practice to get just the right amount of “extra” into that stitch on the right needle before working the next stitch.

Use the right needle to elongate the stitch (check to see if it will easily reach over the gap), then work a JSSBO. After a number of repetitions it will become clear how much yarn you need to pull into that stitch to span the gap and you won’t have to check for each stitch.
