Before - Stash at 100 Billion, Interest is at 10%.
With Bank Fraud Program 1% + Galactic Investment Facility 1%
After Stash at 100 Billion, Interest is 10.1%.
Same goes for Discharge Deflection Matrix + Shield Master for ABS%. Only the Mothership Module has any effect.
Same for Worker Growth I think ... in fact I could almost be confident in saying CP %'s are not being added.
Also .. the documentation seems a little off.
As it stands now you can buy a 1% upgrade in Stash Interest, Worker Growth and Shield Absorb ... And receive 0.1%, 0.01% and 1% respectively. Not sure what to make of it ...
