m15 R3, Windows 10 Home, AWCC 5.8.2.0, Overclock Profiles guide?

AWCC has so-called overclock profiles which seems quite handy; however, I could not find any official guides or documentations available publicly. Profile settings offer three scales: "Frequency", "Voltage" and "Voltage offset" with ranges colored in gradient from red to green. "Voltage" scale can take values from 1.02v to 1.14v colored in all yellow, or from 0.8v to 1.02v colored in all red, depending on a value picked for frequency (the former range is available for any frequency from 4.5 GHz to 5.3 GHz, while the latter is enabled when frequency value is from 3.7 GHz to 4.4 GHz):

1. Am I correct to assume that "red" ranges are unsafe? In this case does it mean that it's unsafe to use any frequency below 4.4 GHz as it makes Voltage all red?
2. Why selected Voltage doesn't scale to Frequency? How could it be that different Voltage values can reliably offer the same Frequency?
3. When applying the changes, AWCC runs some "tests". From my observation any combination of the values always passes, does it mean it won't cause any harm to the hardware?
4. What is the difference between Offset and Voltage when it comes to undervolting? What is safer to change?

Assuming this is an Alienware Laptop? Before our users can assist, they need more data.
Which specific Laptop model?
What operating system?
What version of AWCC is installed?

The model is Alienware M15 R3, OS: Windows 10 Home, AWCC version is unknown
