David,

 Ok.  Pedantically, you are using the OOB in one very small
 sense:  The OOB is where the BBT marker and version is kept.
 So UBI does use OOB in, typically, just two (2) blocks.  ;-)

 In our case, whilst _we_ are like you on our reference boards,
 potentially some people may use JFFS2 or YAFFS, so I suspect
 I will include those EEC-checked bytes in the OOB in bit-flip
 counting.

cheers!
