Pattie was supposed to be on her way to the next guesthouse where she had a reservation, because that is how it works at the Kohechi trail and the other trails of the Kumano Kodo. Strictly organized. You make your reservations before the start.
IMO she took the wrong trail by mistake ~ or someone took her ~ but deviating deliberately from the trail and going backwards instead of forward is not a viable option.
Yes of course. I have done a lot of multi-day backpacking/walking trips, myself.
17 km is not that long a day, when she's been out there every day for quite a while.
There was no necessity for her to get onto the trail at 7 am and march straight to her next destination. She had the whole day to get there. Why would she leave so early?
The place near where her backpack was found, Totsukawa village, is apparently an exceptionally beautiful place:
"Visiting Totsukawa is like stepping into another realm. The landscape — astonishingly beautiful and bordering on fantastical — is covered with lush, verdant mountains that seem to brush against the sky. A bright, turquoise river snakes alongside the road into the heart of the village, contrasting sharply with the stony cliff faces at the water’s edge and suffusing the scenery with a serene, mystical quality"

In her situation, I would want to see that place before I left, since I would probably never return. I and my companions have done similar things on our trips, often: it's morning, we're fresh and full of vim, so lets go early on a quick side hike, up to this fabulous peak/viewpoint, before heading back onto the scheduled route, which is a bit of a boring slog.
Apparently the person who found her things on the trail only walked an hour, although they must have been scanning the edge closely looking for signs.
I think she could well have taken a serious risk in venturing to a higher, dangerous place to get - what else - a view and photos...
