The major plus of that letter is that it looks for tax-deferred income, below-the-radar income (in terms of Wall Street), or other round-about ways of getting total compensation up. It tries to get credit time up, not simply myopically focus on payrates.
Negatives are that it's concessionary in critical areas. T pointed out one. The other is a re-warmed version of "1.5>80", which has been debated ad nauseum, and is a pretty obvious way of steering money from the average pilot, to the flight-ho's.
Who authored it, anyway?
