bunny hopping has its ups and downs, in games like CS:S if you bunny hop and hit the person while your in air, its luck.  end of story, there is no if, and, or buts involved with it.  thats really why you dont see many people doing it.  when you get into the pro sections (CAL:TWL (..well not so much TWL, but mainly CAL) you will see no one even jumps at all.  most "pro's" are to the point where whoever sees the person first wins.  the game is a little harder to get HS's for, and the mechanics of the game are no where near perfect (ie: bullets not registering and doing no damage, lagged people who can circle the map before you've got any weapons, the "scrips" (thats where you change or add codes to the game) that allow things like fast weapon switch and even moving your screen around which is banned from CAL because it gives the player an unfair advantage sometimes, and a lot more.  no game is perfect, hell looks at PS and you have the entire dual coring, still a sh*t ton of bugs that i dont even want to get into.  but to me, if you can get that many headshots, no-scoped or scoped, you are pro in my books, i have a hard time even aiming at people i get so nervious and scared when the time comes, i just flip out and hold down my mouse button while throwing the mouse around the room hoping it will hit the person.
