Could be that the notch depth was obscured by the noise floor of the 
analyzer, coax leakage, or other factors, and you just couldn't see the 
change.  

When tuning a set for the local club, I had the rejects down to where I 
couldn't see the bottoms with my tracking generator at 11dBm and noise 
floor at -70 IIRC, and I had to use an HT for signal source and tune 
the notches that way.  Scary thought when a bit too much input would 
permanently smoke my analyzer.

But, if you're getting enough notch, then it's enough :)
