To all those like myself who thought the Aeon sacrifice system deposited 100% of the units mass into the build project, prepare to have your preconceptions shattered.
Here are the results of my meticulous sandbox testing. What you do with this knowledge is up to you.
General disclaimer. All test were conducted 2 or more times. Most only two times.
Tests using unupgraded SACUs (except for sacrifice). Note: Mass of sacrifice upgrade (150 mass) not included in calculations. Also HP values rounded down to the nearest hundred.
GC (27500 mass): 90000/99999 HP for 27300 mass of SACU (#14)
Paragon (250200 mass): 2100/5000 HP for 251550 mass of SACU (#129)
CZAR (45000 mass): 30700/40000 HP for 44850 mass of SACU (#23)
Tempest (22000 mass): 46200/60000 HP for 21450 mass of SACU (#11)
Salvation (202500 mass): 4700/10000 HP for 202800 mass of SACU (#104)
Tests for RAS SACUs (not preset) with sacrifice. Note: Mass of sacrifice upgrade (150 mass) not included in calculations. Also HP values rounded down to the nearest hundred.
GC (27500 mass): 25500/99999 HP for 25800 mass of SACU (#4)
Paragon (250200 mass): 600/5000 HP for 251550 mass of SACU (#39)
CZAR (45000 mass): 9300/40000 HP for 45150 mass of SACU (#7)
Tempest (22000 mass): 12500/60000 HP for 19350 mass of SACU (#3)
Salvation (202500 mass): 1400/10000 HP for 206400 mass of SACU (#32)
Tests for RAS preset SACUs with sacrifice. Note: Mass of sacrifice upgrade (150 mass) not included in calculations. Also HP values rounded down to the nearest hundred.
GC (27500 mass): 84400/99999 HP & 99999/99999 HP for 25800 mass & 32250 mass of SACUs respectively (#4 & #5)
Paragon (250200 mass): 2700/5000 HP for 251550 mass of SACU (#39)
CZAR (45000 mass): 36100/40000 HP for 45150 mass of SACU (#7)
Tempest (22000 mass): 47500/60000 HP & 60000/60000 HP for 19350 mass & 25800 mass of SACUs respectively (#3 & #4)
Salvation (202500 mass): 6200/10000 HP for 206400 mass of SACU (#32)
Tests using T3 engineers as sacrifices. Note: HP values rounded down to the nearest hundred.
GC (27500 mass): 24200/99999 HP for 27768 mass of T3 engineers (#89)
Paragon (250200 mass): 500/5000 HP for 250224 mass of T3 engineers (#802) = 202680 mass worth of reclaim from wrecks alone.
CZAR (45000 mass): 7400/40000 HP for 45240 mass of T3 engineers (#145)
Tempest (22000 mass): 11300/60000 HP for 22152 mass of T3 engineers (#71)
Salvation (202500 mass): /10000 HP for *** mass of T3 engineers (#) <- Test not conducted. Got bored.
My general conclusion. NEVER use the sacrifice system unless you literally have no other choice. Its better to ctrl+k and reclaim the wrecks.
Have fun out there.
