Data Mining and BI, which is what your describing, isn't an intuitive skill. This is something that is easy to describe, but difficult to implement. I know, because we installed Clickview that can read all our databases, but we're still not getting usefull information months later because our DBA guy isn't an accountant. That is, he can see the raw data, but he doesn't know how to compile it into anything usefull. The accountant just uses our accounting software, so doesn't know the mechanics behind the information that he uses daily, so the two have been doing their 'day jobs' of keeping the databases and finance running, while also trying to build usefull reports; and it just takes a long time.
I would bet $3.10 that AC doesn't have BI software, which means they would probably try to grow their own; even if its only writing scripts within MSSQL, that is still time consuming. And they would still need to learn accounting at the lowest levels.
As an aside, I was playing around with game dev, and the engine I proposed had an economist module built right into the infrastructure. But the game itself was more of a fantasy based world simulator, and not so much pew pew, so it was more critical. The EC mod would dynamically adjusted drop rates based on supply and demand... well, it would have if the game was ever programmed, but it wasn't. Probably because it was so frick'n complicated it would never be released... Perp is released, so at least AC did that part right (not making the programming too complicated to ever be produced).
