In Arsenal, the vehicle modification "Engine Customization" when applied to Acceleration costs Body x Accel x 25. However, Acceleration has two values--walking and running.
So, how do you figure the engine enhancement?
Does it apply to only one value, and the other must be customized separately? (Reasonable, except the long description implies that only one acceleration customization and the other must be used for top speed.)
Do you use one of the walking or running value? If so, which one? And do you increase both values or just the one used in the calculation?
Or do you average the two values and use that in the price calculation?
Or something else yet?
