Okay! I've gone back and redone all of the calculations, and
reassembled the Timeline for the third time.
- There may still be some off-by-one errors, but they shouldn't carry through to other dates (I calculated everything at once).
- Men and Dwarves are in. Galadriel and Aredhel are still out.
- I've tried to explain my reasoning a bit better in some of the notes.
- Every item is footnoted to show which source it comes from. Lower number footnotes are later sources.
I am quite pleased to have worked out a solution to the whole Men/Utumno issue. It doesn't match the Reddit version, but I believe it holds up as a plausible "Final Timeline".
