Question on Resource Enhancements

[Enigma]

What planetary and System-wide enhancements stack values and which do not. For example if I have a planet with both a Robotic Factory III (+30%) and a Mineral Scanner III (+45%). Does it have a +75% improvement in production or does it only take the best (+45%).

Do System Robotic Factories and System Mineral Scanners stack or do you just get the best value of one facility?

Thanks

You get the best Planet modifier plus the best System modifier.

If you combine a (planetary) robotoid factory and a (planetary) mineral scanner, you get:
- +45% to minerals
- +30% to organics
- +30% to rads
for that planet. Plus any system bonuses, which follow the same pattern.

Ok that is what I thought but I wanted to make sure I was not missing anything. Thanks

A couple of weeks ago, Douglas pointed out that Planet and System modifiers did not add, but multiplied instead. So, a +30% planet bonus and a +30% system bonus would end up giving a... +69% bonus (if I get the maths right), and not a +60% bonus.
