If you need to learn about federal sentencing and how federal criminal sentences are figured out, then take a look at this group of posts from PCR Consultants. The first post of four is a primer followed by 3 that go into detail on the complexities of federal sentence computations.
The figuring starts with a beginning number which is founded in the type of crime associated with the sentence. Calculations are then added to or subtracted with enhancements and mitigations based on specific criminal conduct. Finally, the last post details calculation changes based on criminal history.
If you need to take the mystery out of how federal sentence recommendations are calculated, it’s a must read.
