Hello All - I have been home roasting on bullet for 2 months now and finding ROR moving too much even when there are no change in any parameter. This is
resulting into unven roast. Have attached one profile screen shot for reference.
This is normal behavior and is a tradeoff between noise (jagged lines) and delay of the data. If you see a very smooth ROR you can almost be sure that there is a huge delay and that the data shown is something that happened a while ago.
I would recommend that you set your Y2 axis to 25 C. You can do this in settings → Roast Config → Chart Defaults
