We don't recommend mixing and matching the two dosing methods. There are safety mechanisms built in to each one, and studies done on both methods when written as is. The only suggestions for deviation is if using TR with a higher dose kitty with secondary condition, causing the dose to drop frequently. TR also says only 0.25 unit dose changes, but if you read the original paper on it, and the German forum where it started, there are allowances for larger changes in higher dosed cats.
Eddie got to 58 on the AT with 11 units, that's way too low. I wouldn't recommend going back there. I know you are trying to test twice each cycle, but sometimes life gets in the way. With SRT action happening, an extra layer of caution is required.
