@Huinesoron - I think there might be a problem with using the '72 years until adulthood' figure.

The dates of characters' births and marriages in XIII.1 (which we're using as the template for the timeline) are predicated upon the carefully calculated dates in 'Scheme 7' of XVII.

However, 'Scheme 7', up to generation 13 assumes that the differences between the births of parents and children are less than 72 years (from 25 years in the first three generations and getting progressively longer until reaching 73 years in generation 13).

Another problem is the gestation period, which is only 1 year in 'Scheme 7'. Which means that our timeline's Elves have to be 75 years old at minimum before having children: and if we apply this at a constant rate before reaching gen. 13, we get a problem.



Related to the above - I would still change 864/144 to 863/144, and move back the following Valian years by a year, in order to preserve Tolkien's SY. The main reason is the elaborate calculations I mentioned above, who knows how messing with SY dates for the dates of birth of characters would impact those calculations.

Again, I stress that XIII.1 was predicated upon them. (For example, Tolkien's timeline has Ingwe born in 2072, Finwe in 2120 and Elwe in 2126 - pulled straight from 'Scheme 7'.)

It would also shave off 144 years, making the timeline last for c. 5930 years, a bit closer to the SA and TA duration, if not by much. Which might mean that you'd have to jettison a whole VY during the March, something I find preferable.
