It seems like the sort of thing that really could be boring, and so he did not feel like bothering with it. On the other hand, sometime later in the book (I think when he first starts learning Yllish? ) he mentions how he learned the language of the church in a few days. So maybe there is more to the legends surrounding that trial than he let on?

I guess only time will tell, but for now I think I'm more inclined to take Kvothe's word for it than suspect him of hiding something secret and important.
