Just completed two back-to-back 283g batches of HM India Shevaroy Superior in the Variac-boosted Hottop and had no problem producing a steady decline in BT RoR. So that will not be a problem. Keeping the 'Rao ratio' at 25% or below will be a different matter. These roasts, taken to FC+, are at 26-29%. The next step will be to see whether a smoother decline in RoR has provided any improvement in the cup. I still have not found Scott's statement that his 25% goal only applies to City to City+ roast.
