No.
Only if kmiop/kmirl are from factory programmed that they fit in those colums
I have no idea what this means, but if you never want exceed the highest specified load as calculated by KFMIRL, neither KFMIRL or KFMIOP need to be altered.
LDRXN just caps the output of KFMIRL, so if LDRXN is always lower than the highest KFMIRL, then you'll never need a higher KFMIRL.
