CONSISTENCY CLASS
1) Any vehicle that enters into and competes in an MRA class may compete in the Consistency Class. If the MRA class that you fit into is not offered at a particular race, you may enter the Consistency Class. However, if your class is available, you must run your class to be eligible.
2) After two runs, the difference between the two times is your consistency score.
IE: truck 1 runs a 2.500 and a 3.500 his score is 1.000
truck 2 runs a 6.805 and a 7.312 his score is 0.507 and is the winner.
3) All general and class safety rules apply as written for your class rules.
