Pitch Raise Questions

[euphoniac@juno.com]

I am currently a Randy Potter student with some questions about pitch
raising.  When I measure the pitch of A4 with my SAT III, how low (in
cents) should it be for me to need to perform a pitch raise?  Also, when
performing a pitch raise, is it better to raise only the single strings
all the way up, or should I raise all of the strings of each note as I
go?

Thanks,
