The comment of most interest above is the one about logging of flight time. Many private owners just use the tacho or a VDO which is fine, but you are most likely doing yourself out of hours unless the time is measured on an air switch. If you log flight time using your watch noting the airborne time and the landing time that is legal. You would be surprised how many hours you might gain as a result (unless of course your a/c is fitted with an air-switch)
But as they say above - don't over-run the m/r. Unless you have about 10% margin on your trip to allow for the odd diversion etc., then do the check.
safe flying!
