Max level 1/5 mean that no ray got reflected not refracted.

Smpls/Pxl is a ratio that inform you about how much over-sampling was 
done during the render.
If it's close to 1, then, most pixel needed only a single sample to get 
the final result. If it's somehing like 10 or more, that mean that, on 
average, at least 10 subsamples where needed to compute every pixel of 
the image. This don't take into acount partial reflection or chromatic 
dispersion associated with refraction.
A large value may indicate that your antialiasing is to agressive, 
probably from a threshold that is to low or set to zero. If you use 
focal blur, then, that value can only be somewhere between the minimum 
blur samples and the maximum, and can get pushed higher if also using 
antialiasing or blured reflection, that you set in the camera.
