Be cautious with the Timewave concept. There is an inactive forum that have some insights about it here :

There are problems pointed by John Sheliak (and prior to him Matthew Watkins) about the Zero version of the Timewave. Terence acknowledged himself that the re-formalization provided by Sheliak corrected some errors on the Zero version (hence the attribute Zero).
The Sheliak's version don't have a steep fall on the 7th of october although the trend is the same.
So it's clear imo that the concept is in an unfinished state.
