Subject: How do I translate MFM badtrack BFI values to RLL ones?

I have successfully reformatted my old MFM drive (Seagate ST251-1) with
my new RLL 1:1 controller. It all seems to works quite well. In fact it works
almost too well...
During the badtrack scan only one of the 25 tracks listed on my
badtrack list was found. Is this normal? Is it possible for the controller
to correct worse errors when using RLL than with MFM?
(When I formatted it with an MFM controller all the 25 tracks were found)

To make sure I won't get any unpleasant surprises later I would like to enter
the badtracks not found by the media scan. 
Unfortunatelly my bad track list only lists Head, sector and "MBFI".
How do I translate this MBFI (MFM Byte Offset from Index?) value to an
RLL Byte Offset value ("RBFI"?) ?
