I'm almost certain double jump waveland onto smaller platforms is faster, not by too much though.
I recommend you practice double jump fastfall waveland left or right, get this down consistently and you will be able to waveland onto a platform from the air very easily. Then learn the timing for either double jump / full jump waveland onto short platform, this is timing based.
Also Ganondorf's wavelands are incredibly easy; especially his perfect waveland. Do not be afraid to go almost completely horizontally left or right on the control stick when you are wavelanding onto platforms or the ground; although keep in mind constantly doing perfect (full length) wavelands will become a bad habit when learning other characters.
Also his wavedash; remember to practice perfect wavedashes with Ganondorf. I feel like his wavedash is not so great unless you are doing it mostly horizontal; then it becomes a very important spacing tool and not so bad.
and to answer your original question: The distance of the waveland has no correlation with amount of jumps; It's all up to your position on the analog stick and timing. Imagine the control stick as a unit circle. At 180 or 0 degrees you will have a perfect waveland, completely to the left or right. While if you did it at 225 degrees (diagonal left) or diagonal right, the distance will not be as far.
