Greg,

The 3MV/per meter figure was gleaned from a text book on electrostatics! 
 Those guys are dreaming and so was DC Cox.  I thought the 3MV would 
raise some hackles.  I have always opted to 1MV/ meter in air (DC), but 
it is nice to know you have noted an even lower value.  I will amend my 
own work and thoughts accordingly.
