Clarification with FC2 or FC3 stitch

I am knitting a pattern that uses an FC2 and FC3 stitch. It is a personal pattern and their instructions say that if it is the FC2 stitch to move one stitch from your knitting needle to a cable needle keeping it in the front, knit the next stitch on your knitting needle and then knit the 2nd stitch off that is on the cable needle. If that is true, how many stitches would you move to the front cable needle on an FC3 stitch and how many would you knit off? Would the instructions be the same for BC2 and BC3 stitches?

The pattern is doing 2 stitch and 3 stitch cables.

F and B just refers to holding the 1st half of the cable to the front or the back.

On the 3 stitch cables, the pattern really should tell you whether or not 1 or 2 stitches are to be held front/back. If the pattern does not say, then in theory you could do either, just be consistant throughout the pattern. I might lean towards moving 1 and leaving 2.

For a FC3, you usually move 2 stitches to the cable needle and hold in front, knit one from the left needle and then knit the 2sts on the cable needle (the cable moves to the left). For BC3, move one stitch to the cable needle and hold in back, knit 2 fom the left needle and then knit the one stitch on the cable needle (the cable moves to the right). The FC3 and BC3 are “traveling cables”.
For BC2, move one stitch to the cable and hold in back, knit one from the left needle and then knit the one from the cable needle.
