I know this has been discussed before, but I've got some specific references and I'd love an explanation from any ITF chaps/chappesses here....
As I understood Sine Wave (about a month ago), it was down-up-down and you land the strike on the final down portion of the movement. This always felt like although in theory you're adding gravity to the movement (which is a + in force) you're removing the solid connection and ground reaction force (so --- force). Boxers like Mike Tyson strike on the up portion of the movement, and I can understand that adds considerable power.
However, on another site I was in a discussion with someone and they said that you are 50% extended (let's say in to your straight punch) at the top of the motion, and that is when you impact the opponent. The remainder is follow through. This I could understand and agree it makes sense, it's literally impacting at the top of the "up" portion.
I followed up with some resources from General Choi (taking him to be the defining force or authoritative source for Sine Wave) and it seemed that my original understanding was correct.

- In Volume 2 (page 34) of his Encyclopaedia set. He shows that the hip is raised in the middle of the step and drops down from there in to the punch (and in the middle of the step where the body is at the highest, it can only go down from there)
