(oh look, a what-if exercise!
)
Yes. Fun.
The historians will be picking over the moves we made when this war is over with a fine toothcomb, judging us... but will those historians be Terran or Hertak...
Of course, it's far easier to make such a call after we know what the enemy stats are & how many reinforcements they got & when. Hindsight & all 
Indeed. I have no regrets.
Here's another what-if, assume that due to our aggressive 1st moves, the 1st Zy & 1st Fura'ngle arrived one turn earlier in place of the 3rd/4th Cordi (queue-jumpers!)
Actually, I've just noticed the 1st Fura'ngle up there in Algol on turn 1, I missed them before. So, new max damage potential in Kardoen:
1st Nordera Fleet Fighters: 18+8 = 26
1st Nordera Fleet Capital: 15+9 = 24
Fighters at 150% Strength
Capital ships at 150% Strength
4th Cordi Fleet Fighters: 20+6 = 26
4th Cordi Fleet Capital: 12+10 = 22
Fighters at 100% Strength
Capital ships at 100% Strength
1st Fura'ngle Fleet:
Fighter attack strength: 22+15 = 37
Capital attack strength: 28+12 = 40
Fighters at 150% Strength
Capital ships at 150% Strength
Damage - 89/86
I reckon the addition of the 1st Zy could have smashed a fleet without calculating it, but Spoon did pledge not to do the one hit kill at that time, so he'd have probably sent them to Aldebaran instead of Tauri, with the 2nd Zy going to Tauri instead of showing up on the front, I predict.
Let's see anyway:
1st Cordi Fleet Fighters: 30+9 = 39
1st Cordi Fleet Capital: 18+15 = 33
Fighters at 150% Strength
Capital ships at 150% Strength
1st Zy Fleet:
Fighter attack strength: 33+16=49
Capital attack strength: 32+17=49
Fighters at 150% Strength
Capital ships at 150% Strength
3rd Cordi Fleet Fighters: 20+6 = 26
3rd Cordi Fleet Capital: 12+10 = 22
Fighters at 100% Strength
Capital ships at 100% Strength
Damage - 114/104
Yeah I thought so, but it wouldn't have happened.
