Help for a newbie - Python On Cold Side!

[CALM Pythons]

Perhaps this will help explain whats going on;
I am no longer using the night bulb lamp at all. It has been disconnected and is no longer in use.
The day lamp is plugged in, but is kept off at all times unless the tank requires a bit of a heat bump or I need to see inside the tank (the room the tank is kept in is not illuminated very well)
I was told that the CHE being over the top of a hide would turn it into an "oven" and that I should not position it so. A 20 long, while reasonable, isn't really THAT big so I am forced to place the CHE in the middle.
I probed the hot side hide and got a reading of 100.5 degrees. Too hot. I suspect the CHE being on the hot side had something to do with that, but I also dialed back the dimmer on the UTH very SLIGHTLY just in case.
I plan to probe both hides again this afternoon and this evening to stay on top of the changes I am making.

I also covered both sides, the back, and the top with DOUBLE LAYERS of aluminum foil secured with black electric tape (I have NEVER used tape INSIDE the enclosure )
After I finished that, I added cut planks of pressed and painted wood to the OUTSIDE of the aluminum foil on the tank's back and both sides for additional insulation (I did NOT use cardboard).
I then misted down the whole tank with warm water, topped off the water dish, secured everything, and snapped the following pictures.

Please let me know if you have any thoughts or suggestions.
I'm desperately trying to get this right!

Yes that was me that said to move the CHE from above the Hot Hide...only 1 source with a UTH for basking. My names Chris
.. Excellent job.. Good idea with the insulation. It looks like all you need to do is dial in the dimmer now for the Hot hide.. And yes your right the Hot side probe got up to 100 because of that CHE.
Also remember when your dialing this in do so when you havent removed the lid for several hours.. You'll have a heck of a time with that dimmer unless you only adjusted one thing at a time.. If your moving the CHE around, turing Off & On the light ect ...that will all effect that hot hide probe that we need to get the UTH regulated with. So dont correct 2 things at once or you'll never know what should be raised or lowered.
Remember a couple degrees at night is nothig to worry about, thats natural. So when your ambiant goes down at night (when house does) your UTH may go down to 87/88. Thats fine.
Sorry if I rambled, ive said so much i dont know what I said or didnt say yet haha
