See, there you go showing your ignorance. I use an infrared heat gun. I can check mulitple enclosures and know that each temperature recorded will be calibrated with the same gun. You can't do that with thermometers. Each can give you a different reading. So, to answer your questions, no I don't guess, I use technology. You ask me whether it doesn't really matter? Do you honestly think you have any of the answers, much less all of them.
Unlike your precious carsheets, I don't monitor my humidity. I have water bowls that provide enough humidity. Do you honestly think that these snakes live in controlled temps and humidity in the wild? So what if my humidity ranges from 40-70% at times. I know my snakes don't, but you probably do.
When you have a 1600 gram snake in a 32 qt enclosure, you don't have room for a hide. They are all in racks with solid sides, so if they want they can dig under the paper to hide but they don't usually.
See how much you can learn by listening? Stop talking and listen to us. We've been giving you the correct answers, but you continue to insist it has to be your way.
From your descriptions, THESE SNAKES ARE NOT BEING ABUSED. The husbandry is different than you've read on caresheets, but they are okay. Maybe not ideal, but okay. Stop preaching until you've read the Bible a few times.
