PPM moves and Form 3903

I'm finding a lot of mud in the guidance for Form 3903 and Pub 3 when it comes to PCS moving deductions, and I could use some help.

We were paid in '25 to do an OCONUS DITY in '24. I compared the PPM Statement of Expenses to the W-2 and everything checks out. Great! But... now I'm confused in doing our taxes.

The numbers between the PPM checklist and the 3903 will be similar, but it seems like some are in different categories. The way I understand 3903 is that Line 1 is how much we spent to move our STUFF. Line 2 is how much we spent to move US. If adding those two lines together is more than the 12 P line in the W-2, then we can deduct the additional expense. If it's less, than this is just an exercise in frustration. :) But there are things, like lodging, that are paid out of a different (non W-2) pot of money. The 3903 seems like they should still be included in the calculations, until I read this - "Also, don't include any expenses that were reimbursed by an allowance you don't have to include in your income." So does this mean any expenses covered by the travel voucher should NOT be counted on the 3903? (If that's the case, why do they specifically call out lodging as a calculable expense?)

I'm obfuscating numbers, but overall:

W-2 paid 25k, withholding 6k and deducting another 6k of expenses (box 12 P)

Line 1 includes the moving truck, local packers, moving truck's fuel, weigh tickets, tolls. - 5k

Line 2 includes our POV mileage (x 2 because we moved both cars), hotels (one night at old assignment, all hotels en route, and one night at new), tolls. - 2k

Line 3 = 7k

Line 4 = 7k-6k=1k
Moving expense deduction = 1k

Am I right?

Side quest question - If our paperwork said the military anticipated spending 40k for a non-DITY move, why were we *only* reimbursed 25k? This was before all of the newfangled DITY nonsense of last FY, as we completed the move in summer of '24. (And, yes, I'm very content with 25k. I'm just curious.) We were 3k under our weight limit.
