I couldn't agree more with this.
Trying to use formulas and exact calculations to operate in volatile terrains is pretty much a waste of time.
All you really need to know is that you need to let the tyres down. The terrain can change from one day to the next.
Sand is a perfect example. The change in humidity can decide which pressure you need and even which gear range you need to select within just a few hours!
There is currently a "which range should I select?" thread happening elsewhere. It's the same for that.
If progress is impeded or your vehicles hurting, you adjust accordingly.
I would also add, this is why we are out there, to test, try, experiment and have fun doing it.
