Green at the top of the load only happens if you have too much material in the chamber. Restricted heat flow reduces convection temperature as the vapor exits the device, leaving the very top exposed to lower max temp. As most of us have figured out, this thing works a lot better with a fluffy/loose load. With unrestricted hot air flow, the material at the top of the chamber encounters the same temperature as the material closest to the heating element and you end up with @Mr Mellish type uniform results even on 1.5 (with newest heaters).
Uniform gold on 1.5 instead of dark brown with it set to "kill" at 3+
I hadn't given it much thought but suspect this is true. My material is relatively fluffy and I have never tamped it down at all; drop it in and seal it up without any pressure on the material. Bingo.
