The Modifying Sub-Categories (MSCs): (What you do with it)

MSC Guidelines:

1. MSCs must be considered during all Jeep encounters, and wave patterns must be adjusted accordingly.

2. MSC 5 is the median - the accepted norm.

3. MSCs from 1 through 4 will increase score as listed.

4. MSCs 6 and 7 will decrease score as listed.

MSC 1: Top off; vehicle, driver, and all occupants covered with mud: +30
MSC 2: Top partially off; vehicle and some occupants covered with Mud: +20
MSC 3: Top on; vehicle covered with mud: +10
MSC 4: Top off during snow, sleet, hail, or heavy rain: +5
MSC 5: Somewhat dirty: 0
MSC 6: Obviously recently washed, but immediately re-muddied a little: -10
MSC 7: Clean, dry, unscratched, untested: -30

Equipment Adjustments (EAs) (What you build)

Consideration must be given to the current mechanical condition of the vehicle, including all modifications for trailworthiness, comfort, appearance, and spouse-appeasal. These are known as Equipment Adjustments (EAs). EAs are a complicated category, and often difficult to appraise under certain conditions (passing head-to-head at 60 mph, when covered with mud, etc) but must be used to modify score when feasible. If a vehicle is so covered with mud that you are unable to ascertain any of the EAs, you MUST assume that the EAs, when combined with the MSC 1 adjustment, would place the vehicle in a higher scoring position than any non-MSC 1 Jeep, and immediately initiate the wave. Otherwise, EAs will adjust score as follows:
