You're looking at a different version of the DMG :)
DungeonsTOME is based on the DMG from 5e.
Although if there was enough interest, I might implement those rules minus the dungeon dressing/encounters and some of the "unusual shapes".

As for the older DMG rules that you have, I'll post them up if I end up implementing that version. Otherwise I'll cause confusion :)
