Unfortunately, the experiment failed to take into account that mere decrease in T4 and RT3 -- per se -- won't do much to help if whatever T3 you have is pooling in your blood (as measured by serum level) instead of going into your cells.
It's akin to taking Avandia to 'help' with blood glucose levels instead of changing your diet to reverse diabetes type 2 by making your cells more insulin sensitive. The Avandia lowers glucose levels all right -- it does so by sending a signal to the tiny pre-fat cells hanging around the gut that makes them become full-fledged (empty) fat cells, and then sends all the converted-to-fat glucose into them. The patient grows ever more insulin resistant, until even the fat cells become resistant. Then Avandia won't 'work' anymore.
The whole idea of first diagnosing and then properly treating thyroid hormone resistance is to make the cells more thyroid hormone (T3) sensitive instead of letting them remain thyroid resistant. Selenium supplementation won't do a darn thing for that.

Does anyone know where rT3 is created? Is it the thyroid only? I don't have a functioning thyroid.

First, most of your T3 is created in the liver and kidneys, which is why it is called a
peripheral thyroid hormone. It's created in peripheral tissue rather than in your thyroid gland.
Second, it is created from T4, but if your thyroid is not producing T4, no conversion can take place. However, T3 taken orally can go directly into your cells (assuming the receptors are not blocked by RT3 -- and only a blood test can determine that) and be used as if it had been 'converted' from T4 to begin with. Unfortunately, most doctors are still prescribing Synthroid or other T4 meds, and those only add to the problem if T4 is being converted to RT3. That medication is not really suitable for almost anyone.
Dessicated thyroid, which contains all the four T's your body needs, has been used successfully for over a hundred years, and only a huge Big Pharma campaign ten years ago (or so) shoved it into the corner. If you do not have a RT3 problem (as shown by blood tests) -- then dessicated thyroid is great. The best out there right now is Nature-Throid or Westthroid (made by RCL Labs) -- and the worst is the newly reformulated Armour, whose current cellulose fillers are causing major medical problems for patients.
Finally, you may be surprised to learn that not all thyroids treated by radiation (as yours was) are totally inactive -- or if they were initially, that they need to remain that way. There seems to be a growing population discovering that with the right supplementation of peripheral thyroid hormone medication, some function can be restored. There's a fair bit of research out there on the net, and there are blood tests you can order that will tell you where yours is currently.
