I found some twisted numbers for the metopb coeffs in the calibration.py script.
'metopb'
'bh' 1.478 -> 1.748
'bl' 1.478 -> 1.748

I further checked metopa, noaa18 and noaa19 - these are correct!

Very good that you found it! Maybe that is causing all the problem with Metop-B calibration.

Might be of interest for you. The plot shows the mean of the low and high calibration slopes for the day since launch until 2019 for MetOp-A CH3A.
