*scratches chin*

The GvtEff number isn't working properly because the min/max tech is already built into the formula. That is just applying a fraction to a fraction for no reason....

Without wasting a ton of time testing formulas on a day I'm busy, it's pretty clear the GvtEff needs to be set to 1 to get your desired result rather than 0.65. I'm not sure why the formula is listed wrong, but if Max tech is built in to the formula already, I don't think a fraction would get applied to the end result.
