Hi Bart,

I monitor the current in two places - right out of the variac and 
going into the pig.  Without any PFC, the two currents should be the 
same and they aren't.  I have reduced the difference by changing the 
wire routing but I also suspect the two meters just plain "dont read 
the same".  When I get to it, I will swap the meters to see if the 
difference follows the meters or is dependent on where the meters are 
located.  Anyway, let us know if the twisted pairs helps.
