This is really quite entertaining...
If the "hot spot" on your heat mat is a full 65% of the mat's surface area...why not set your thermostat probe to the "hot spot" and forget about it?
First-I didn't call YOU anal-retentive, I said the activity was anal-retentive...which it is. I am also very anal-retentive in certain activities regarding the upkeep of my snakes...I believe that everyone involved in this hobby MUST be to a certain extent. It is the nature of the beast.
Second-I(and several others) started out giving you our personal opinions of the situation, to which you took offense, and insisted that our opinions were wrong, and yours was right. It seemed from the outset that your only intention was to complain about the percieved "poor quality" of the mat, and not to get solutions, advice, or input on the situation. You certainly didn't seem to be accepting of ANY opinions outside of your own. Anyone that claimed you might be over-analyzing was immediately met with comments such as your response to my bad typing:
83-95? Are you trying to cook your snake?
Your response to the suggestion that you simply remove 2 of the three thermometers, and allow the snake to use it's natural, innate, and instinctive ability to detect thermal gradients:
And what if I DIDNT check the temp across the whole mat? What if I only used one thermometer and it read "78." So I bumped it up so it would read "86" in that spot. But 6 inches away the hotter spot on the matt would read 94 degrees. I would of never known the irregular temperature difference and the snakes health could be in trouble.
And I won't even get into how inapprpriate some of your responses to TandJ are...regardless of a different conversation in a different location with him. He was STILL only trying to help you here...which is why I accentuated "in this topic" when I
originally made the comment.
The bottom line is that there were several people, including myself, who were very nicely and very simply(not to mention politely) trying to help you and provide you with more accurate information than you were displaying. When we informed you that it wasn't a big deal, you informed us that 93*F was going to kill your snake(wrong). When we informed you that you were worrying about something that you needn't be, you informed us that it was a health risk(wrong). When I informed you that variances in any and/or all of the equipment combined would account for a mere 9* variation, you reacted with:
I am stating a point that compared to my T-Rex heat mat that I have for my other Corn, the Exo Terra Heatwave is NOT nearly as stable. I can put the probe anywhere on the T-Rex and it will be about 1 or 2 degrees within anywhere on the mat. Not so for the Exo Terra.
All I was trying to do was even out the temps for the Exo Terra so its not such a dramatic change.
Again...9* is NOT a big deal...
especially after considering the NEW information that the "hotspot" is a full 65% of the mat's surface area, and the
fact that a thermal gradient is something to be
strived for, not fought against. (not to mention the very nature of heat mats and the dissipation of heat by physical properties and out of necessity

)
I could care less which heat mats you use, how you attach them, or what methoids you use to micro-manage your snake's environment. It's your snake, dude...do whatever you want. If you want 7 heat mats, 7 thermostats, and 24 thermometers strewn across the bottom of a 20L aquarium so you can be absolutely sure that your snake isn't too hot or too cold at any given time of day...go for it. I (and several others), were very simply(and politely, I might add) informing you that it was unnecessary, the temperatures were ALL within acceptable "hot side" ranges, and that you should just relax and enjoy your snake...which seems to be a very reasonable response for us to have had to this topic, if you ask me.
Unfortunately, you didn't want to hear that. You wanted us to provide you with a means by which you could manage your heat mat down to a 1* difference at all times, and quite frankly...I don't think such a situation exists.
Whatever you want to do, dude...it's your snake and your headache. The bottom line is simply this: if your hot side is between 80-88*F, and your enclosure is of appropriate size for your snake...you won't be risking your snakes health in the slightest. If your hot side temps occasionally reach 90*F or slightly higher for several hours during the day...your snake will STILL not be at risk, so long as there is a nighttime drop and a full water dish.
Someone said to pick your battles...quite simply...this topic needn't have become a battle. You could have either accepted the general consensus that your micro-management was unnecessary and moved on, or you could have ignored us and found your own way(you said yourself the tile was working...what's the problem?) Nobody needed to get all riled up about anything...and you are the only one I see getting bunched about the waist. When faced with opinions and facts that were different than your own, and those you
believed to be true(mistakenly), you overreacted...just like you overreacted to a 9* difference in a mechanical heat mat...
