I'm sure I don't have to point this out to you but that's not going to give us anything like average numbers for a #5. Decent method for pulling something out quick though. I tried to start figuring it out at BR and gave up after 5 minutes 
Yeah, I spent about 20 seconds thinking "is there a database of #5 starters? No, because I don't even know if half the teams had a consistent one." Detroit's a great example of the "#5 starter" being a myth - they bullpenned a prototypical #5 (Coke) for a trade acquisition, so there's nobody who had the spot with regularity.
