Fast track same as Rise, I already asked, not sure about the rest though. :-)
On the XP point breakdown, at the end of Edge of Anarchy, if the PCs do everything, they will ding 4th at the conclusion of the final encounter if on the medium track (Which is what they are supposed to be in accordance with the intended design).
Admittedly, if the Fast Track is used and Eel's End is resolved through roleplay, the PCs should then ding 3rd after the Shingle Chase and before the Dead Warrens starts.
My reason for doing the breakdown was to figure out how much slack there was in the design for additional encounters, and switching to medium track and adding a 5th PC, whether I could expand the 1st volume significantly by adding in ~15,000-25,000 XP worth of CRs.
Answer: YES. Assume Eeel's End is resolved via roleplay and that there are 5 PCs instead of 4, all progressing on the Medium track, you can then add 25,000+ XP to Vol 1 safely.
