The MIG readings did not change appreciably from before relaxing to =
after, so the nominals should be updated at this point.  The wonkiness =
is probably due to insufficient relaxing before saving nominals the last =
time.  Normally a single relax sequence would do it, but the day before =
there had been the error that Dan noted (going to 0,0,0,0,0,0,0 in Galil =
numbers rather than setmir).  Repeating relax sequences until the MIGs =
do not change much would be a good idea after correcting an error like =
this.
