94.68.85.36 here, its good to note that by efficiency and duration i mean BONUS stats not the 100% default

Also,you will need maxed out streamline and all 3 duration mods to reduce the cost to 25%

182% bonus duration and 30% bonus efficiency

Cost = (2.5*0.7) / 2.82 = 1.75/2.82 =~ 0.62EPS (2.5/4 = 0.625 which is the lowest possible not 0.62)
