Okay let's get to basic first.
1. If I understood your reply, you assumed I or my friend uses 'Area mode' AF tracking when comparing the 85 f/1.4D versus the 85mm f/1.4G?
No.

2. 50% that my shots are OOF? Meaning not focused to where I intend to? I get it focused where I want it to be. I shoot only in single AF point mode. If it is the eyes, then it is the eyes.
Excellent !

3. Based on my experience with the 85 f/1.4D, it acquire focus faster than the 85mm f/1.4G. But hit rate aren't as good as the f/1.4G despite being faster.
I guess I need to get myself a 1.4G and shoot more.

4. Depending on condition, sometimes the 85 f/1.4D can't even get a lock under low light, hunting compared to 85mm f/1.4G. To be frank, have you tried the 85mm f/1.4G and comparing it side by side with the f/1.4D before? If you did, you would understand what I experience.
Never held the AF-S 85mm f/1.4G before. If under extreme low light, I only rely and use the 15 cross type sensor to focus.

This I would agree 100%, have used my friend's 85 f/1.4D many times already before getting my own 1.4g
1. Focus accuracy @ 1.4 is way better than the 1.4D under low light
2. Focus speed i think is almost the same anyway ( Way slower than 70-200 but not unbearably so )
3. Focus accuracy improves once stop down ( I guess it's the same for any prime lens? )
4. Sharpness for 1.4G wideopen is generally a bit better than 1.4D, but not shockingly better as the 1.4D is quite usable wideopen
My conclusion is same with CY, under low light condition the D version hunts and miss focus much more frequently compared to the 1.4G version, there's just no comparison at all

Agree on all accounts except for #1. I would they are about equal and would depend on how you handle it.

if G is worst then D what is the point of nikon make these new lens

That's why I mentioned that I will not refuse if you give me the new AF-S 85mm f/1.4G to replace my AF 85mm f/1.4D.
The one thing I like (and miss) about AF-S lenses is the ability to override the attained final focus manually if required by twisting the focus barrel.
