(1) Except as otherwise provided in this section, for an offense enumerated in part 2 of this chapter, determine the recommended minimum sentence range as follows:

    (a) Find the offense category for the offense from part 2 of this chapter. From section 22 of this chapter, determine the offense variables to be scored for that offense category and score only those offense variables for the offender as provided in part 4 of this chapter. Total those points to determine the offender's offense variable level.

    (b) Score all prior record variables for the offender as provided in part 5 of this chapter. Total those points to determine the offender's prior record variable level.

    (c) Find the offense class for the offense from part 2 of this chapter. Using the sentencing grid for that offense class in part 6 of this chapter, determine the recommended minimum sentence range from the intersection of the offender's offense variable level and prior record variable level. The recommended minimum sentence within a sentencing grid is shown as a range of months or life.

    (2) If the defendant was convicted of multiple offenses, subject to section 14 of chapter XI, score each offense as provided in this part.

    (3) If the offender is being sentenced under section 10, 11, or 12 of chapter IX, determine the offense category, offense class, offense variable level, and prior record variable level based on the underlying offense. To determine the recommended minimum sentence range, increase the upper limit of the recommended minimum sentence range determined under part 6 for the underlying offense as follows:

    (a) If the offender is being sentenced for a second felony, 25%.

    (b) If the offender is being sentenced for a third felony, 50%.

    (c) If the offender is being sentenced for a fourth or subsequent felony, 100%.

    (4) If the offender is being sentenced for a violation described in section 18 of this chapter, both of the following apply:

    (a) Determine the offense variable level by scoring the offense variables for the underlying offense and any additional offense variables for the offense category indicated in section 18 of this chapter.

    (b) Determine the offense class based on the underlying offense. If there are multiple underlying felony offenses, the offense class is the same as that of the underlying felony offense with the highest crime class. If there are multiple underlying offenses but only 1 is a felony, the offense class is the same as that of the underlying felony offense. If no underlying offense is a felony, the offense class is G.

    (5) If the offender is being sentenced for an attempted felony described in section 19 of this chapter, determine the offense variable level and prior record variable level based on the underlying attempted offense.

    (1) For all crimes against a person, score offense variables 1, 2, 3, 4, 7, 8, 9, 10, 11, 12, 13, 14, 19, and 20. Score offense variables 5 and 6 for homicide, attempted homicide, conspiracy or solicitation to commit a homicide, or assault with intent to commit murder. Score offense variable 16 under this subsection for a violation or attempted violation of section 110a of the Michigan penal code, 1931 PA 328, MCL 750.110a. Score offense variables 17 and 18 if the offense or attempted offense involves the operation of a vehicle, vessel, ORV, snowmobile, aircraft, or locomotive.

    (2) For all crimes against property, score offense variables 1, 2, 3, 4, 9, 10, 12, 13, 14, 16, 19, and 20.

    (3) For all crimes involving a controlled substance, score offense variables 1, 2, 3, 12, 13, 14, 15, 19, and 20.

    (4) For all crimes against public order and all crimes against public trust, score offense variables 1, 3, 4, 9, 10, 12, 13, 14, 16, 19, and 20.

    (5) For all crimes against public safety, score offense variables 1, 3, 4, 9, 10, 12, 13, 14, 16, 19, and 20. Score offense variable 18 if the offense or attempted offense involves the operation of a vehicle, vessel, ORV, snowmobile, aircraft, or locomotive.
