Temp recording significantly different between front panel and what computer displays/records

Last few roasts (am still a newbie) there is an obvious difference between what front panel is displaying and what computer is recording via the IBTS, ROR can be off as much as 30-40 deg and final bean temp records a different value.
Has always seems a time lag exists between front panel display and recorded data but doesn’t seem to explain all observed discrepancy.
Just wondering if others see same behavior or I’m missing something.
Thanks.

The IBTS ROR is additionally filtered in RT which could be why there is a difference. The IBTS bean temp should be the same on RT and the front panel.

Thanks for reply. Using RT v. 4.8.1 and installed firmware 615 not to long ago. Unsure what could be going on. For example stopped last roast at 420F on front panel but RT recorded stop point as 415.
ROR curves completely non-sensical, RT will show going from +50 or so ROR to a -5 in seconds and back again, none of which is consistent with front panel display.
Did re-install USB drivers from within RT, will see if makes any difference. I didn’t see any settings within RT/config etc. that could account for this.
Thanks,

Thanks @luderjk.8cot . This looks like some rendering issue. I can see the values in your actual profile look correct . Here are the final values in C from your last profile.

We will look into things for you.

Interesting, because recently discovered sort of similar issue, during roast I would offload at particular temperature, lets say drop temp during roast would be 212 degrees, but once I drop beans and roast finishes it records it as 209 final temp. Could also be firmware?
