I read this for my bookclub and only finished it for that reason. It could have been written in a linear way and been a better story for that. Towards the end if the book I ended up having to reread some earlier chapters because I couldn't fit them into the overall narrative. And like one of your other reviewers, I skimread the final chapters with their awful detail. The only non linear writer worth reading is Lawrence Sterne, who got away with it in Tristam Shandy, but then that was a funny book.
