I'm not good at math, but I can tell you the real issue.
The issue that is debated here is the fact that SOME doctors will not treat a patient untill their TSH is over ten.
That is wrong. At the very least, if your TSH is above labratory test limits, your doctor should run anti-body tests.
If your TSH is one pinch above range and you have anti-bodies, you should be treated, because anti-bodies + above limits is a diagnosis of Hashimoto's. Period.
Waiting till your TSH is above 10.0 is ignorant.
We all know that once you are diagnosed with a thyroid condition, the doctor SHOULD try to get your TSH down around 1.0, and then fiddle with your levels until you feel well.
Many GP's will start treating you as soon as the TSH test comes back with a little H (for high) next to the test result. They look at the results and say "Hmm...you need a little Synthroid". They may not even bother running more tests. They go by the H's and L's on the paper.
Unfortunately, many doctors think that a TSH of 4.0 is good just because it is within range, and let you hang there on meds instead of increasing the dosage to get you closer to 1.0.
Diagnosis and treatment levels ARE different. But the difference should not be as great as some doctors feel it should be. And the treatment parameters are not always well understood by the doctor.
Just my two cents worth.
The treat for the second Natural hormone should be:
Treat=2nH+ or - 1nH or Treat= 2nH (body produces none)
forgot the minus
