I was trying to make a spreadsheet to track the German Pz and wanted to calculate the amount of fuel they receive each turn to help with understanding their potential, as an assistance when planing the defense as the Soviets. So, based on the info from the manual, i came up with this formula, but the numbers are wrong compared to the tests i made, the Pz receive more fuel in the tests.
FuelReceived (in %) = 1 * MPMultiplier * DistanceInHexesMultiplier * MovedModifier * AxisRailModifier
Is the formula ok, and if so, were the coefficients that are used to calculate each of these changed without updating the manual maybe? Do the commanders make rolls for supplies, thus adding a random element? If some of the more experienced players could help, i would be very grateful.
