must make a tentative determination of the Guideline sentencing
range as soon as practicable after the case is referred for preparation
of the PSI Report. If the probable sentencing range for the offense(s)
or conviction is unlikely to exceed 4 - 10 months of imprisonment and
the defendant is detained, the Probation Officer must:
(a) Give priority to the expedited preparation of the PSI Report.
(b) Promptly inform the Court of such determination and of the
completion date of the expedited PSI Report so that the Court
can determine whether the sentencing date should be advanced.
