(FB=I) means flashbacks are in sync with island(I*SW) means the island and sideways are not in sync
(Wild Card) means island and sideways world are both correct.
The context of LOST can vary depending on the final Context. From this analysis, it is more probable that the flashbacks and island time lines correlate. Jacob infers such as he has watched the candidates, and the island characters have referenced their flashbacks.
It is interesting to note the wild card possibilities:
the Flashbacks and Sideways are real and the island is not; and
the Flashbacks are false but the Island and Sideways are real (but in different dimensions?)
The finale needs to confirm one of these story constructions otherwise the context of the characters actions cannot be considered in their true light.
