Narrative:

2 pilot reports in aircraft logbook. 1) right standby engine egt indication reads low. 2) right EPR flashes .39 in digital window. Analog portion of reading normal, standby normal. Entire display ok 9/10 of the time. Both items were deferred, and though all engine parameters worked normal on the second EICAS compartment, it was (aircraft) released with a misinterp of the MEL.
