In the old days of early efis airbus (A300) if was part of the prefight prep to extract a toga value and compute a flex value from the QRH based upon the assumed temperature from the performance chart.The assumed temperature was selected on the thrust rating panel and it computed an N1 which was checked against that on the bug card This plus the appropriate speeds were written on the bug card and then checked by your colleague.
In the less paper world of fbw Airbus ( no computation of power settings by the pilot) the target thrust appears in the upper right of the EWD and when you state thrust set you should compare this value with the actual thrust set. This is meant to have been achieved by 80kt. I doubt most airbus pilots would know roughly what a typical value of toga would be or the N1 for a full derated take off.
