Good Morning,
I need to do a stat avg on the time difference between results. Problem is all of my fields are both duplicate and multi-value (MV). 
So, 
1) Will the fact that every field is duplicate & MV affect the avg? 
2) How can I efficiently make all of the data show up as a single field?  This has to be within my search query because its a production environment and I do not have access to change how the data coming in.
Your data is probably JSON and you are probably creating index-time fields because you are using INDEXED_EXTRACTIONS = json.  This is all fine but when you do that, you need to make sure that you set KV_MODE = none for your sourcetype or you will get a 2nd search-time field extraction/creation which will duplicate and multi-value everything.

Thanks @woodcock where would I find this to be able to edit it?
It should be in props.conf on your Search Head. You need CLI (no GUI for this).
Thanks : D
