No, lyngsat is no help for this. Someone simply took the press releases and threw the channels up, with some basic knowledge, and voila, it became the bible.
However, that bible has wrong information. For example, Dayton has the networks available from 119 (sharing a transponder from Louisville), but three of the other channels are coming from 101 (sharing the Cincinnati transponder).
Lyngsat has all Dayton from 119, which is incorrect.
I can honestly say I know more about DirecTV and their transponder usage than Lyngsat does.
