iPhone app increase shake gesture sensitivity

Question

In my iPhone App I have used shake gesture it is working but it requires lots of efforts to shake.

Is there any way to make it more sensitive?

Here is the code

 - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
 {
      if (motion == UIEventSubtypeMotionShake)
      {
          [self performSelector:@selector(startPressed:)];  
      }
 }

The isnt a way to do it directly as far as I'm aware.

One way to get around this would be to use the accelerometer's readings, and then decide for yourself if it was a shake, you would be able to fine tune it yourself if so.
