To reply to your points in order:
1) I don't think anyone truly believes you talked to mentors from Balance to make this doc. If you discussed it with them you could credit them for having given you insight into all of the jobs in the game for you to then use that information to create this document.
To the next point. We aren't using buffs "early" we're using them when it's optimal and where we get the most burst out of them without holding them forever, for example, you're expecting WARs to use 8th GCD IR which is just awful, especially if they don't have NIN/MNK in their group (and if they have MNK your openers would still put Brotherhood out at the 5th GCD meaning IR now misaligns for Brotherhood which is the only buff that perfectly aligns with IR, and IR is 1110 potency more than 2 Inner Chaos uses, and that's without factoring in Onslaught and Upheaval and the autos you get under it). To your point of GNB using Gnashing earlier, that kind of doesn't matter. I don't say it as like "Tank optimization doesn't matter" I mean that the things tanks do to optimize their damage doesn't affect the raid because they aren't putting out raid buffs. So PLD dropping an Atonement after their req window to ensure they go into Maelstrom with a stronger combo doesn't affect the raid at all, it's a personal optimization to mitigate lost uptime.
2) I'm actually going to do a counter question. What actual benefit does delaying the openers give? Currently going through every opener I can for the jobs I have a role for in Balance, every job using the openers in Balance hit their most important/highest damaging skills under raid buffs. Battle Lit, used on 3rd GCD, covers all of DRG's highest potency moves while also ensuring the raid gets everything they want under those windows. A lot of what I see on your list would make jobs lose potency under your suggested buffs and I'm inclined to believe that my thought is correct considering how many people have come and explained and shown proof of how they lose potency under your suggested alignment (even more so when the people telling you that your suggested alignment is a DPS loss are people that I know are mentors on Balance).
