I would be inclined to say keep the dose at 0.1u, unless the appetite is still an issue. Mid 80s are still safe nadirs, and the rest of the tests are still where it seems 0.1u for a little while longer would benefit her. And, as Marje mentioned yesterday, the 0.25u can affect numbers for up to six cycles. But if you feel more comfortable trying the drop dose and seeing how she does, you can certainly try that, and go back up if you start seeing numbers trending upward. Has testing gotten a little easier?
ETA, I should have also noted, technically, with SLGS under 90 does earn a reduction, and you did have a bit of dry in the mix today, for very good reason since you had to leave and wanted to make sure she would be ok, so if you want to keep following SLGS, then it would be better to give the drop dose.
