what is idle power EPR? less than one... but EPR on the engine on reverse is higher than one, it's difficult to compare just with a known value in your head ... I've never looked at the EPR on landing and thought it was too high or low... also because the idle-EPR value changes for each regime of flight. There's no time... you only look whether the reverser is green! then you monitor speed! They did see the speed was high but did not know why!!!
