The CSV file with all of the roast data doesn’t seem to match the data shown in RoasTime. This is a sample from one roast at the 1min mark. RoasTime shows an IBTS temp of 84.2ºC and I-ROR of 51.8ºC/m, whereas the CSV shows 82.38ºC and I-ROR of 30.04ºC/m. The bean temp/ROR is also off.
The IBTS ROR CSV data gets even wilder at certain points, e.g. -14.95ºC/m (CSV) vs. 29.9ºC/m (RoasTime) at 01:40.
If I make a graph from the CSV data, it looks very different to what’s shown in RoasTime (mostly the IBTS ROR):
Is this somehow expected? I am not sure which data I should trust.
Note: RoasTime numbers seems to match Roast World, and the CSV seems to match the data returned from the API.
