I am familiar with the concept. I was taught it many years ago. It has both benefits and drawbacks. For one it telegraphs the move. That is the main reason why it is not used in many styles. The gain in power is not worth telling the opponent that you are attacking. That being said effective techniques do not necessarily need that extra power. Even light techniques can have a devastating effect if done correctly. I regularly stun (nearly a KO) my students with only light strikes. It is more in where and how you strike than in ho hard. If the, as you call it, wave works for you great. Just be sure that you understand the drawbacks.
Best of Luck!
EDIT:
The wave is not really up-rooting as was mentioned by Jas. That used to cause the attacker to lose his balance by rising up. Another disadvantage of the wave is that while you rise at the beginning, the opponent can take your balance more easily if he simple attacks at that point. Of course he would need to be close enough to do so.
