I found the multiple encounters listed sequentially (by necessity) but playing out in a non-sequential manner to be a bit confusing.
Add to this the red herrings, and I began to lose track of what the paths the PCs could take.
To make things a bit easier for myself, I created a visual map of the encounters. It's not super accurate and not always clear, but I know it's helping me understand connections between sites and encounters at a glance, rather than flipping around through the book, or scrolling through the pdf.
I've published the google docs Wati First Events, and Wati Second Events, in case others would like to use them or are interested in making something similar (since deciphering my own map could be tough if you didn't build it).
For me, it allows the PCs to have a non-linear approach to the problem, while allowing me to have a connected sequence of events quickly at hand!
Great charts Phin, thank-you for sharing!
