I wouldn't be surprised if it were more accurate based on the errors I've seen. I always eyeball the books and was confused when a £15k building popped up on our asset sheet. It turns out a "workshop" had been categorised as a building we had purchased, rather than the training session it actually was.

This is the importance of having layers and multiple sets of eyes on things, though. Even if it had got past me, my accountant would have surely queried it at year end, but that could be true of an LLM mistake too.
