so this is how much you need of every science pack for all of the research
automation-science-pack: 54715
chemical-science-pack: 45600
logistic-science-pack: 54180
military-science-pack: 27920
production-science-pack: 20725
utility-science-pack: 28350
So to reach productivity modules 1 you need:
automation-science-pack: 1130
logistic-science-pack: 840
To reach productivity modules 2 you need another:
automation-science-pack: 2160 (-8% = 1987.2)
logistic-science-pack: 1580 (-8% = 1453.6)
chemical-science-pack: 375 (-8% = 345)
To reach productivity modules 3 you need another:
automation-science-pack: 4360 (-12% = 3836.8)
logistic-science-pack: 3145 (-12% = 2767.6)
chemical-science-pack: 650 (-12% = 572)
production-science-pack: 300 (-12% = 264)
