ROTFLMAO!
Unbelievable. You're probably the only person in the world who would unapologetically use altered tables in something like this. I suppose the fact that degrading the Shivan's beams would also have the effect of making the Sathanas's rear LRed less effective wasn't a problem then? 
Now that you mention it it will take it 2 more seconds between each shot...not that that will affect the battle in any significant way. I did use modded tabels but the total differences shouldn't add up to more than a 5% total gain for the Orion in firepower in this scenario..
Hell, I can repet the mission with clean tables, but as I told you before, I did a similar mission when I first got FS2 and it stil lended up the same way.. Not that it matter..
And the LREd can be easily destroyed by the Orion - resulting in hte Orion being hit once, and hte Sath loosing it's rear cannon and having it's belly exposed.....
We never see that kind of pinpoint accuracy in the game. Why are you using it now? Furthermore why are you only giving this ability to the terrans? Yet again you're continually stacking the odds in favour of the side of the argument you are on regardless of how fair it is.
Think again. I've seen many times during the game that sometimes capships target weapons..especialyl on the Sath since it's a big target (and even more common if they attack the sath from the front, since it's the closest system/turret for them to target)
The entire argument between the two of us is as to whether a single Orion and kill a Sathanas. If you are willing to conceed that it could only happen if the Sathanas pilot was a complete idiot I'm willing to end the matter here.
In that scenario yes...and possibly in another one.. You see, the Sath captain doens't have to be a idiot - he can just be sure of himself.
For instance, he can try and turn around immediatley... or he can try to bring hte rear cannon to bear.
That agressive tactic sounds far more logical for Shivans than running for 15 minutes while the enemy is shooting at you and then turning around.
Now all by itself those two tactics aren't bad... IF they work. They can work, but there's no guarantee.. Of course, in order to win the Orion's captain has to be a good one. He should take out the rear cannon if possible and try to stay at the saths side or below it.
If the rear cannon is lost the Shivans captain would probably try to bing hte front ones to bear by turnign immediately. that probably won't work well, but how long will it take for hte shivans to abandon that tactic? How much damage will the sathanas take before that? It's engines compromisea big percentage of it' HP, but if it's spends several minutes trying to catch the Orion in it's weapons arc it will suffer quite some damage....and how much of that damage will be to it's engines? slowing it down..
If the Sath's captain starts the pull away and turn tactic then, then the Sath is in far worse position - it's allready taken some damage (? of it to the engines) and it's running from a Orion ow can again, shoot at it's engines, slowing it down...increasing the time it takes for it to pull away enough...and again giving the Orion more time to hit it's engines...
I'd say a Orion has good chances to win in this scenario too, but I wouldn't call the Sath's captain stupid...
