I guess that last sentence is what you’ve been trying to reach at.

I hope you were not serious in comparing the 3As of Chan’s with Asada’s. In Vancouver, her 3A in SP looked marginally OK, but both of her two attempts in LP should have been downgraded. If other female skaters adopted the same cheated techniques (pre rotations to backward takeoffs and under rotated landings) as hers from their early ages, we would be witnessing many of them claiming 3As by now. I don’t consider Asada a good jumper at all except for her hit-and-miss, and marginal at best, 3As. She’s definitely inferior to someone like Ando, let alone Kim or Kostner, in jumping techniques.
Back to Chan, what’s wrong with trying to have multiple quads before having reliable 3As? It (having the 2nd or 3rd quads at hand) would only help stabilize his 3As, at least psychologically, as it would give him options when his 3As are not working well.
I think, barring injuries, he can really dominate, with the kind of skating he has. He has no equal among his contemporaries in skating skills. One live look at his skating two years ago made me a believer, instantly.
