Comments: How does TntMPD determines monthly average?

We had a church that was giving $1,000 per month, then stopped in June 2010. So now we are trying to raise our support to fill that gap. How do I remove that church's previous giving from the average to find out my current actual average is. I considered deleting the church as a contact, and their giving, but I like having that on history, just don't want it included in my current average to see how close I am to getting the support we need.

TntMPD doesn't currently offer a way to exclude certain contacts from the total average.  But on the anlaysis page, if you drill down, it does seperate total averages between those w/ pledges and those without pledges (special givers).
