Gosh MEA, you seem to be a little stressed.
If the MR has an entry that says: "GPS nav data base to be updated no later than 1 January 2013", and it's now past 1 January 2013, take 3 deep breaths and relax.
I'm good friends with people who would be happy to fly that aircraft, day VFR, with the entry still 'open' on the MR. I'm happy to sit in the back of the aircraft.
Those people regularly fly aircraft with a few entries open on the MR. Those people are also suspicious of MRs that have no entries. So am I.
