What is current thinking about Oht and Nox gaga? Given their position in the list, I am wondering if Ohtgaga is really Jute-gaga i.e. the Meon Valley? And if Noxgaga is Oxford?

Also what is the significance of the subtotal, the adding up of some of the hides to 66,100? Was it just a carry-over like the scribe was counting to the bottom of the page? Or is there some political significance, like the Mercian king got the 66100's geld but the others were tribute kingdoms that could not be relied on or didn't pay their hidage directly to the King of Mercia?
