These are, after all, merely records of barometric pressures at select points over the area of a whole country. They serve as an indicator of the barometric pressures governing the weather systems governing the country's weather as a whole at the time. There have doubtless been other very high pressure systems in the intervening years, and equally it's very likely that this has been one of the highest (on account of it breaking records where pressure has been recorded) but we don't really have to be absolutely certain that it has been the highest ever by any particular measure.
