How is the DPS value calculated?

I'm interested to know which factors affect the calculation of the DPS number. It seems from some minor experimentation that adding mods which boost Accuracy or Crit Damage increase your DPS score, yet Stability does not.

This minor experiment yields some odd results when equipping weapon mods, as to me it means that a DPS focused build would just stack lots of Accuracy and Crit Damage, but there must be more to it than that. As that would make most other mods pretty useless.

To me a high Stability score would mean more shots landing on target due to reduced recoil which would surely increase your damage. Whereas a highly accurate assault rifle, for example, with low stability fired for a sustained period wouldn't land as many shots, due to it needing far more 'manual correction' to compensate for the recoil.

To compound matters, there is a loading hint which even states that DPS isn't the be all and end all of if a weapon is good, and to consider other aspects. Which is very pertinent when considering my First Wave M1A with both Balanced and Accurate talents.

If this is the case then why, when browsing weapon mods, are these 'other' bonuses not made apparent to the player through the UI?
