I too was having serious issues trying to get my draw shot to work. I was cueing so far below center that sometimes I was jumping the ball and generally miscueing a lot. Now, when I wasn't miscueing, I was getting ZERO action on the ball 90+% of the time.
I went to my local shooting buddy, Bob Nunley, who also happens to be a BCA Instructor. I told him my problems and he said.....and I quote....."Let's set up the camera and shoot some shots. In 30 minutes you'll be drawing it half the table."
In LESS than 30 minutes I was drawing the ball like I'd never drawn in my life. Turns out I was dropping my elbow a solid foot on draw attempts.
So, in my estimation, I was cueing too low at times because I thought "if I can just hit it low enough it's GOTTA draw back here...." which was causing miscues.
And on the rest of the shots, my elbow was dropping so far down, that the cuetip was coming up WAY above where I intended it to. This caused virtually no action on the cueball.
So, while anything is possible, the issue is probably your technique.
I suggest seeing a qualified instructor who will videotape you.
Now that I know what to look for, I watch EVERYONE in the room shoot. It was an eye-opener. Most people have some serious issue somewhere in their PSR routine, stroke, finish, etc. I always want to say something, but I figure they'll either tell me to go pound sand or they'll take my advice and their game will jump up....which makes it harder on me.

So, the only person I really say anything to is my best friend, who took the BCA lessons with me. We keep tabs on each other, let's just say.
Disclaimer: I'm not a BCA Instructor, but I have shot in one's basement.
