vpd has 3 things, stage of grow, humidity and temperature. So if you can setup your environment to best possible conditions - you are golden. Table is one for all, but equipment we all use different, so i don't get your question, you need math teacher for correcting or you want reassurance of vpd table ???
you are on the other level than most in control, so 60-70 in veg don't work for you, wait a bit, there is definitely geeks of growing. Somebody will come up
try to contact those two, this platform has chat, right bottom corner - press arrow.

Do it to it!
You'll figure it out as you go. It looks like you already have a grasp on it. All that's left it is to dial it in with a grow or two and you're golden.
Good luck!

Thank you Anonymous2022
For now, i can only control humidity.
I will be adding a heat source to get night temp up, for less temp swings. (if anyone has a recommendation for plugin heat source for grow tent, inbox me)
But for keeping temp down, is it a struggle.

Hi there
Personally I wouldn’t be adjusting the humidity/temperature this way..
I would be trying to keep the temperature around 28 but if it drops or goes over slightly its not a big deal..
Humidity I would be trying to do higher in veg 60-70%
In flower lower the humidity around 50-40. %
Best of luck 🌱

Additional information:
I have a co2 bag.
Max temp 30
Min temp 20
Temp will most likely rise to max 31 (Light is on 75%, will go 100% next week)
The temps recorded are ambient room temp.
The temp in the VPD chart has adjusted the temp -2* Degrees celcius to leaf temp
