QPFRADJ option 2 vs option 3

I think the "good support" people at IBM have the week off.  I opened a 
sev 1 domino issue and got call back only.  This person I got says I 
should be using QPFRADJ option 3 instead of 2.  And, he swears that it 
does adjust at IPL time still.  Judging by his accent perhaps his reading 
comprehension of the help has issues also.

Does option 3 adjust more timely?
Does option 3 adjust at IPL time?
Is it not a good thing to adjust at IPL time?  I can imagine that if you 
do not want to automatically adjust at IPL time because that major 
application isn't using up the resources yet therefore an adjustment at 
IPL time would just give resources to dead stuff and then be choked when 
the major application kicks in (like Domino).
