Your RT3 is high, but your FT3 is high, too, and it's the ratio of FT3 to RT3 that's important, not raw numbers. In my opinion, your numbers do not show RT3 dominance.
Your FT3 is is high, and that needs to come down some more, even though it was even higher in April (please verify those FT3 numbers for April and July). At the same time, your FT4 is below range and has to come up. I think you should talk to your doctor about decreasing the Cytomel and increasing the Synthroid.
