I don't really understand where you are coming from on this airyana?
The brief covers all those points that the pilot flying it feels are relevant. If it is the second time in two days that the pilot has flown that approach with the same person, he may well refer back generally to the previous brief and only highlight the minima and tracking as well as any additions to the Vref that may be factored in because of the weather on the day. On the other hand there may be notam, traffic, operational or other factors that require a briefing change from one day to the next.
It is a fundamental mistake to assume that this is some sort of "parrot type" narration that needs to be judged from one persons performance to the next. A companys Standard Operational Procedures will lay down the skeleton of the points to be covered for a normal brief. It is up to the individual how much "meat" they want to put on those bones.
You appear to be soliciting various individual performances for the suggested benefit of discovery? Given the obvious and the variables, I am not sure why?
