the all time records uses the instantenous data
but the averages/extremes information uses the 1 minute averaged logged data
(so hence the differences)
Really ??? This 'confuses' me. Surely a maximum is a maximum is a maximum. The label on the Averages/Extremes report says 'Maximum Temperature', so surely this is what it should be reporting, ie the actual top temperature recorded throughout a day, and therefore agree with the value as reported on the 'Monthly'/yearly/all time extremes...
