Ok, so I finished my global reread and timeline, and there are several points that I cannot remove (here is my spreadsheet file with relations between dates):

    * In AGOT, Tyrion comes back from the wall way too fast, and Catelyn moves up from KL way too slow, yet it is necessary for them to meet in in the crossroad inn
    * Cersei knows about Tyrion Waters some three months after he is born, yet, it's hard to compress the timeline further so the riots happened 3 months later.
    * In AFFC, Cersei burn the tower of the hand a lot of time after Tywin's funeral, that does not make much sense, yet it has to happen after ASOS Arya 13 and the rape of Saltpans.
    * Stannis arrives at the Wall extremely fast, considering when he gets the news, yet I had a hard time making it longer, as he needs to rescue Jon, and Jon cannot fight Mance for months.
    * Sam, due to the speed of ships, should arrive in Oldtown very late in year 300, yet by then, the captain of the huntress tells him that Cersei is still in command and the Redwyne fleet is still bogged down somewhere. I guess it could fit if Cersei were to somehow become free and reassign the fleet elsewhere, but it's a bit far fetched. Compressing time would mean, yet again, teleporting ships, and even then Sam needs to synch with Arya, and this means not being in synch with Cersei, arg....
