HDSLR: Luimix GH6: can I use 200p for the 180° rule?

Hi,
I often use my GH6 always in semi AUTO. I set it 50p and I shoot at 1/100. Therefore I let the camera decide the aperture and ISO settings that I configure with a range of 100-1600.
I always use a variable ND filter (VND). Usually I am happy with this way.
Recently I was in Africa on a plateau at 1700 meters high and the solution and the altitude fooled me. ahahahah
In fact all my clips were slightly overexposed. Luckily I shoot in 4K 4:2:2 and I recovered all the colors of the clips without problems in post-production.
All this because the camera could not go below 100 ISO and could not close the aperture beyond that allowed .... I think it.

At this point I ask:
if I were to return to those places, could I always shoot at 100p anmd to shoot at 1/200 to always remain faithful to the 180 ° rule or somehow I can get some concern?
Thanks for any advice.

You are right, in fact I have an excellent VND filter but I hadn't closed it completely thinking that it would alter the colors too much.
On the other hand I thought that the GH6 had chosen the aperture and ISO automatically. But I was wrong.

Out of curiosity:
most likely I will return to Africa and will have to shoot like last time, at 1 pm, around lunch time.
Is there a filter tu put on the lens to soften those hard shadows on people's faces? The clips I have taken the first time, even those correctly exposed, have unnatural "hard" colors. The violent sun of Africa over the red earth at certain times of the day takes away the desire to film, but you have to do it because certain events are right outside around lunch time. ;)
Thank you.
 
The reason why that 180 degree rule was in place was because movement had to have an appropriate balanced look to it. If you can achieve that balanced look at a lower shutter speed then go for it, but if not stick to 180 degree rule letting in more light in the camera. Main thing is with any image, you can't make everyone happy. The footage of the Moon Landing is awful to look at now, but had it not been there, we wouldn't know the history of what went on in the moon.

A friend of mine told me: Cinelike D usually works better than V-Log because it "squeezes" the dynamic range of the near-highlights and highlights / "whites" in a way that when the software "extends it back", you have much better gradation and color detail, because it wasn't ruined due to the too low quality of each video frame.
But he doesn't know Panasonic and V-Log. I don't know if it is right.

Your Gh6 can capture over twice the dynamic range of rec709. Depending on the picture profile you use the camera can capture all the dynamic range ( Vlog ) or the camera decides how to fit what it records into rec709 range. If you use Vlog you can decide how you want to fit the recorded image into rec709. The straight colour transform does a mathematical fit but all the data is there in shadows and highlights for you to expand to create the look you want. If you let the camera decide by using a picture profile that does this before recording you will loose most of this flexibility. Cine D or Cine V still need you to shoot correctly and will need grading. Cine D and Cine V have some sharpening and colour profiling. Just different to Vlog which for most has none. If you want to get the most out of the camera use Vlog as you will have to grade all of them anyway. If you want to be more like a camcorder use Like709 picture profile and the camera will decide but then you will have less flexibility to alter later.
 
Ron,
I also thought what you wrote, but I needed confirmation. Now I am more confident shooting in V-Log.
I don't know how to thank you.
I wish a Happy End of the Year to everyone.
