I didn't. I said that making up/getting numbers you can't even find on the Internet is pretty pathetic. 100s of teratons to 100s of gigatons is a thousandfold reduction, pretty significant.
Nobody made up any numbers. The Venator's terrawatt yeilds and the Acclamator's gigawatt yields are both verifiable cannon.
Means nothing of the sort and you know it - one turbolaser shot is not the same as the whole ships' armament.
Says who? You? Nothing says that the ship can't apportion that power to its batteries as it sees fit. But lets say we split the energy available between all the Venator's. The had 8 DBY-827 turbolasers as and per the source it could "divert almost all of its reactor output to its heavy turbolasers when needed," its heavy turbolasers being the DBY-827 mounts. The reactor output of a Venator was 3.6 × 10^24, the source not being made up internet claims but rather the
Star Wars: Complete Cross-Sections published book which is well known and accepted canon.
So we are clear, the ractor puts out:
3,600,000,000,000,000,000,000,000W
Or in other words:
3,600,000,000,000TW
The source said that the Venator would divert "almost all" of this to its heavy turbolasers so lets be conservative and assume half of those terrawatts are needed for other things. Keep in mind that the qualification "almost all" means that the power available would far exceed half of the reactor output, but I am being conservative to discourage later quibbling.
So with the number halved the power available for the turbolasers is:
1,800,000,000,000TW
Assuming each of the 8 mounts (dual, so two turbolasers each) gets equal power that means each one can project fire bolts with yeilds of:
112,500,000,000TW
Now we can argue all day about transmission loses and whatnot, but at the end of the day the common SW cruiser is yeailding batteries of weapons dropping yeilds that as far as we know are greater than all the firepower of the Covenant and humans in the HALO universe combined.
And at any rate that's the problem with contradictory sources - this is a less precise statement than those that just say "200 gigatons" as the other source does, and several sources put lower ranges on even the "newer Imperial ships" (for instance the fansite stardestroyers.net has numbers at around 1 gigaton...)
Make your choice, at first you are saying numbers from the interent are not usable and now you are appealing to them as authoritative. And the SD.net site gives 1 gigaton as a LOWER limit of minimum firepower, it does not in any way speak to an upper limit.
But you said to use primary sources, and I did.
Not going to ask for a citation since I know there's no clear number - but it is clear, not in any single battle could the Empire bring that much to bear. 1000 ships from a Halo verse Fleet could stand up to a Star Wars fleet and if anything the evidence points to the Star Wars fleet ending up outnumbered because they don't field that many ships at once. And again, I'll give it to you the Covenant aren't undefeatable of course - but then again the Flood is stronger.
Considering the Empire has hyperdrives that make crossing the entire galaxy a couple days travel worth of effort, what exactly is keeping them from concentrating millions of ships at a single spot? Hell, the ON FILM Battle of Coruscant showed upwards of several thousand ships in one battle, so you are pretty much demonstrably wrong on this point.
