Since last patch.. the success rate seems shockingly low.. I have not tested thoroughly.. but it's at the point that I may need to rip out this mod..

Can we get a Mod Setting for the Old success rates?

The module calibrator has slightly better yield than a recycler and an electromagnetic plant filled with legendary quality 3 modules, if the yield is measured by the number of outputs per input that have gained quality levels. It also has slightly better yield by number of outputs that did not gain a quality level. I encourage you to verify by calculating the yield.
