24 cents is out of the normal.  Even with a common pitch raise, it is 
uncommon to find the lowest bass strings at 24 cents deviation, unless 
the previous tunings had been done at something other than 440.   When 
adjusting pitch by this amount, you have to do something out of the 
normal.

If indeed the bass and treble are detuned by this amount, that would 
have been helpful information to know in advance, and would explain why 
my bass and treble did not stay put between the time I finished and the 
time it was scored.  Had I known the bass and treble were detuned by 
that amount, I would have treated the tuning in those areas more like a 
pitch correction.  Despite that strings are detuned alternatively flat 
or sharp, an overshoot of 6 cents would have been required to have 
offset these detuned strings.

There's nothing stable about 2 passes to correct 24 cent deviation if 
the examinee is not aware there is this much deviation.

Also, I find it more difficult to tune the high treble, when there's 
this much deviation.  Under that pressure, when the beats are so fast 
you can't hear them, and in those frequencies, it becomes difficult to 
tell when you are and are not on.  Particularly with the hotel room air 
conditioner going : )

(can you guess which sections I scored lowest on?)
