Varying Weapons Accuracy

[Suicide Junkie]

Also, is there a way that I can get Time Distortion Burst V as Terran? I've tried scrapping the Sallega ships that I've captured, but I never seem to get this tech. Any advice?

Also: scrapping is not what you want to do.

The scrap order strips the ship down and gives you resources.

You want the "deconstruct and Analyse" order, which will give you no resources, and +1 level for each researchable tech on the enemy ship that you don't have.

You don't have to have the prerequisite techs to gain the tech on the ship, but it cannot be a racial tech that you haven't purchased.
IE: You can Analyse a ship to get Phased Polaron Beams, without having researched Physics, but you can't get Organic Armor without the Organic manip trait.

As for the accuracy effects, yes there is a difference between some of the weapons.
Incinerator beam: +10%
Wave motion gun: +30%
Point Defense: +50%

There are a few others as well. If you look in the components.txt and do a search->find for the weapon, at the bottom on the entry "Weapon modifier" is the bonus accuracy in %.

A number of mods add a point describing the accuracy bonus in the abilities section of the component portrait (right click on a component to view)
