Audit Completion Letter - now what

I received an audit completion letter yesterday. How long before I can expect a refund or how long before I know whether they have flagged my case for "Risk Tool Analysis"? I have been audited every year for the past 5 years, but this year is seems like they are dragging their feet.

If you are going to be audited in the next round you will either receive a call or a letter in the next couple of days, else you should receive your refund probably within 5 days or so.
