Yes, i know that now. i just couldn't believe you'd use more vias than  
needed, esp. when it is so obvious. The ground planes explain that.

About the LC meter, it is that one with the morse code, i actually looked  
at that before i bought the benchtop RLC meter. But i decided the morse  
code is way too awkward for me. A LED display will sure make it a lot  
better. Well, too late now for me, the meter is bought. It also does  
parasitic parameters and is very accurate, so it was still a good buy.
