Hi Tara,
Thanks for the quick reply. Are you sure that it's list size that determines it every time? If so, are you able to expand on that at all? Is there a known hard threshhold?
I'm a bit puzzled at this point. Upon testing again, only the two lists that were a couple hundred leads a piece were maintained and the others, ranging from ~1,000 to 13,000 were dropped. This would lead me to believe your statement.
However, the original clone that sparked my question produced different results. In that scenario, the large 13,000 list was maintained.
