i can usually get 3 ki blasts in, depends where i hit my opponent, i multigenball them if they stop in the air, and i ki blob if they are near a wall, floor or the ceiling. But yeh kama, i can usualy get in 2-4 ki blasts on even the most skilled opponent, not everyone has realised there is a way to stop ki blobs hitting you when you get knocked back. On the floor though, pros dont throw straight at the ground anymore, thats something a newbie would do, thinking they can kiblob the opponent. Even throwing across the ground, you can still ki blob someone, just like Hybrid said
on topic: ki blobs were in the show, it was done throughout, sometimes it was smoke, sometimes it was a huge explosion which didnt explode until a final charged up beam had hit it. Vegeta did it many times, Gohan did it on Frieza form 3 after Frieza stabbed Krillen with his horn, Goku did it to Cell during the Cell Games
