I think I found the $1045!
Add $1354 $1395, & $1434; the E-4 pay rates for 1996, ’97, ’98, and it comes to $4183, the high 3, and then multiply by 25% (10 years x 2.5%) and it equals $1045. Using the same formula with modern pay rates, my RAS amount would be $2394. Once the high three is created, does it ever change?
Does the chapter 61 pay rate ever increase over the decades to compensate for inflation?
I went to the COLA historical chart and multiplied the $1045 by the COLA amount from each year from 1999 to 2025 and my amount increased to $2109. That doubles my orginal amount. DFAS probably never bothered to update the amount because it never mattered. I have not followed the amount over the years. My CRSC now should double to $1758 with a 30% DOD and a 70% CRSC, but
drops substantially with a 40% to only $1318. Glad I am not any higher than 40%! I still do not understand why I get more CRSC with a lower DOD?

This is not how high 3 works. 2 members here answered your inquiry. Using your RAS, your offset "$1045" and your DoD% (40%) tells you what your high 3 is in today's value.
1045 / 40% = $2612.50 (high 3)
Now I acknowledge that noones answering why with lower DoD% your crsc payout is higher. Its basic math. Let's establish the numbers.
Longevity pay is 25% of whatever your high 3 is.
Current value of your crsc.
DoD 40%
1045 / 40% = $2612.50 (high 3)
2612.50 x 25% = 653.13 crsc
Exactly like the crsc calculator.
So why DoD 30% is higher?
1045 /30% = $3483.33 (high 3)
So 1045 if its 30% of high 3, the high 3 is larger.
3483.33 x 25 % = 870.33 crsc
Exactly like the calculator.
If 1045 was a DoD 10% payout, your high 3 is 10,450 x 25% = 2612.50 crsc payout.
If 1045 was 50% pay = high 3 is 2090. 25% of 2090 is 522.50.
Dod 75%
1045 / 75% = 1393.33 (high 3) x 25% = 348.33 crsc
