Temperature question

[Homebody]

Odd issue maybe... I just setup a new rack. I have herpstat set to 90 and left it on overnight so I could check temps in the morning. My temp gun says most of the tub is at a fine range on the hot end. Within a degree of 90 one way or the other. There is one small spot on all the tubs where I guess it sits against the heat panel tighter than the rest of the tub and my temp gun is registering 4-6 degrees warmer. ~95-96 on the top tubs, 93-94 on the tubs where the probe is taped. The spot in every tub is maybe a square inch big.

Is this going to cause an issue or is it fine given that its such a small spot? The only fix I can see would be setting up 2-3 more thermostat probes on the same rack so there's only 1 level between the probe.

What type of rack do you have? Is it homemade or did you purchase it from a manufacturer? If so, which manufacturer? I doubt a one inch spot at 96 degrees will harm your ball pythons, but maybe there is another way to fix the hot spot.
