Old Kickr Core vs New kickr core power discrepancy

Hi everyone,

I replaced my 2018 Kickr Core with a new 2022 Kickr core and I’m not sure why but the new one seems to read lower than the old one meaning the same power output feel notably more difficult. The bike and gearing stayed the same, just a new kickr core that for which I have the latest software and did the factory calibration for. I suppose I should just work the new numbers but it feels like I lost 10-15% of my FTP since moving to the new trainer. Did anyone experience a similar thing when changing the old kickr core?

Thanks all for your input.

quite possible that the old one was over reading power by a small amount, someone I know went from an older kickr to a neo 2t and their power was reading lower
