Daniel,
Per your suggestion, I created a new table, quote_usage, and changed the
config files to look at it instead.  Things appear to be working now. 
Thank you very much for your guidance.

Is there any documentation that goes into more detail regarding the 'map'
settings, what they mean, etc., of which you are aware?  I was rather
hoping to avoid digging through the code just to satisfy my curiosity.

Thanks again.

Chris
