[Star Wars] What effective power output is expected of a small-arms blaster?

I'm trying to compare the effectiveness of blaster technology compared to the slug throwers of yore. Energy of their solid projectiles is trivial to calculate, but I'm having an issue figuring out the effective power output of a comparable blaster, say the E-11 for instance. Does anyone have solid data on joules per shot?

Ceteris paribus, the driving factor behind the power of a blaster is the amount of gas used per shot. That said, many blaster models had variable power settings, allowing for the user to make the decision on power vs. shots between reloads, as the situation dictates. Take, for example, the E-11 blaster rifle. It included a stun setting, a low-power/rapid-fire setting for suppressive fire, a full power "kill" setting capable to blowing fist-sized chunks out of hardened duracrete, and many smaller gradiations in between. 

Figured the actual joules of energy delivered for an individual shot is a difficult task. Going by the duracrete blasting power of an E-11 or some of the heavier blaster pistols (General Solo's customized DL-44, for example), I'd put it up there with thr power of the larger, man-portable anti-materiel slug-throwing rifles (assuming they are using non-explosive rounds).
