I wouldn't take any of the combat equations as gospel. As attacks against entities etc and implemented, its likely any equations seen now will be changed. Stick with a more comparative review between weapons rather than the pure damage they do.
Could I hope for blasters being "normal" and lasers+ being armor piercing being able to damage hulls, blaster having a 10% reduction to armor. that's basically how it is in the movies, Blasters blow small chunks out of the walls or scorch marks.
