Calculating the average wait time for a book on hold at the library (or "Why didn't they teach something useful like this in library school?"

Is there an equation for figuring out the average wait time for a book on hold at the library. Or how to figure out the average wait time I have left for a book I put on hold because I'm dying to read the rest of it.
There's a lot of things I learned from working in libraries but the skill I really wish that I had was calculating the amount of time I'm going to have to wait for a book on hold. After reading a couple positive reviews for the Night Circus I put it on hold and forgot about it for awhile. Problem is I just ran across the Free Preview on Google Books, read it on my lunch hour, and am now impatient (but too cheap) to continue through the rest of the book.
Checking my library account hold list, I see that I am #13 on the list of people requesting this item. But in looking at the other details in the record (I never worked circ and metadata/taxonomy/IA is more my side of the street), now I'm wondering how I could use those details to calculate the average wait time:
I'm #13 on the wait list
The system has 29 copies in circulation
5 copies are due to be returned this week
4 copies are either in transit or waiting on the hold shelf and the system has a 10 day period for hold items to be checked out.
Would these be enough details to figure out an equation for how much longer (one average) I'd have to wait to read the rest of the story? Bonus Question - I'm sure OPACs probably don't even take into consideration this question, but is there even a calculation for this sort of thing? Or is that more in the world of Netflix queues?
