These curves have nothing to do with grid current, Peter.  Whenever grid 
current flows in a grid driven amplifier, linearity is compromised.  More 
grid current equals more non-linearity. 
- So far, the 'body of opinion' appears to consist of:  Messrs.  Chadwick 
and Rauch.  Are there others who say that more grid current equates with 
less distortion in grid-driven service?.
