Specifications cars!

[Artyom888]

Good day, please tell me! 
I would like to display the characteristics of the car when choosing it in a car dealership. 
Tell me how I can display such a characteristic as the controllability of a car based on its handling table.

local tableHandling = getVehicleHandling ( vehicle )

function handling( tableHandling  )
	if type (tableHandling) == "table" then
		VehicleInfo.specs =  {
        speed =  tableHandling.maxVelocity /1000, --max speed
        acceleration = tableHandling.engineAcceleration /100, -- acceleration
        control = (tableHandling.tractionMultiplier + tableHandling.tractionLoss + tableHandling.tractionBias  /10) / 5, -- handleability
    }
	else 
		return  
	end
end

 

So I wrote such a code, but it repents to me that it is not correct in terms of calculating the controllability of a car (not a valid formula). As a result, I need to get a value from 0.1 to 1 in order to display it on a scale in the future.                                                                                                                                                                                                                          Sorry for my English(
