Dw should be 0 us
I make my cs to around 25-30us
Which in ppm terms Could be anything from 12 to 30 ppm estimated only of course
Can use ohms law to estimate how much silver was lost or donated to the 
process... but how much was ionic is another matter.
To be honest even a weak brew 5ppm is good.. so don't worry too much at this 
stage

Peace to all

Thank you all for helpful replies.
I liked the idea of measuring conductivity of DW as well as EIS.
If we know the initial conductivity of DW and final of EIS, what could be the 
ppm ? in micro-siemens ?
