The right settings for enhance v2?

Hi,

first of all, the two options “Speech” and “Background” are somehow confusing. Do I understand the following correctly?

Speech 0% means no change? 100% maximum improvement, mabye Robotic?

Background 0% means strongest change, 100% no change?

1. So the logic is the other way around, Correct?

2. If you record at home, e.g. with a ShureSM7B, what are your settings that normally work well in a non-silent but quiet environment? In my experience 90%, 10% is somehow not optimal. 70%, 100%, for example, sounds more natural...
