Miles Messervy Speed Modifiers*
The MMSM system was introduced during the High Velocity Duelling Car Wars PlaybyEmail League in 1997. The rules have been in playtest for almost seven years, but they have not changed significantly in the last three or four.
The MMSM system was developed as an alternative to Car Wars Compendium's targeting modifier
due to speed. The modifier is based on relative speed, and is designed to
encourage not simply *going* fast, but rather carefully maneuvering to *use*
your speed to the best possible advantage.
 Place special turn key next to each vehicle, with arrow pointing
in direction of travel.
 Drawing a line between the centers of vehicle counters, you will
note that a percentage (50% or 100%) of each vehicle's speed
contributed to the relative speed.
 Multiply each car's speed by the percentage on the turn key, add
if they're both on the blue side or both on the green side, subtract if
one is blue and the other green. This gives the relative speed.
 Modifier is 1 per full 15 mph of relative speed and is applied to
both vehicles, so there is no need to figure it again if both cars are
firing.
*These rules are commonly used in ALL RMADA matches except for regional tournaments.

Multiple Movement per Phase
 A car is allowed to make multiple movements per phase.
 Maneuvers will be assigned a difficulty value equal to the difficulty of the maneuver plus
the number of maneuvers preceding it.
EXAMPLE: a D2 bend as the first maneuver is D2 + D0 since
there are no preceding maneuvers, as the second maneuver = D2 + D1 (1 preceding maneuver), etc.
 Maneuvers can incur a momentum penalty, depending on the direction of the immediately preceding maneuver.
The momentum penalty equals the difficulty value of the immediately preceding maneuver and is incurred in the
following situations:
 Current maneuver = bend
Previous maneuver = bend in opposite direction
 Current maneuver = drift
Previous maneuver = drift in opposite direction
 Current maneuver = bend
Previous maneuver = drift in same direction
 Current maneuver = drift
Previous maneuver = bend in same direction
The momentum penalty is in addition to the sequential penalty.
EXAMPLE 1: Car M has 2 'inches' of movement. On the first inch, Car M
takes a D2 bend to the right, incurring a D2 penalty. On the second inch, Car M
then takes a D3 bend to the left. The total penalty for the second maneuver is D6 (D3 + D2 + D1). The car receives a total of D8 for the phase.
EXAMPLE 2: Car A has 3 'inches' of movement. On the first inch, Car A takes a D1
bend to the right. On the second inch, Car A then takes a D1 drift to the right. Total maneuver penalty
for the second phase is D3 (D1 + D1 + D1). Finally, Car A takes a D3 bend to the left. The
total maneuver penalty for the third maneuver is D5 (D3 + D2). Total penalty accrued in the
phase is D9.
EXAMPLE 3: Car R has 2 'inches' of movement. On the first inch, Car R takes a D3 drift to
the right. On the second inch, Car R takes a D4 bend to the left. The total penalty is D5 for the
second maneuver (D4 + D1), D8 for the phase so far (D3 + D5).
