The blog attempts to track the gold added to the game for a new player whilst also tracking the gold required for existing players to maintain their position. It was initially intended to try to work out the amount of gold needed just to stay still in each update. I don't think I am counting things twice (except in the possible error) but I might not have been that clear about what the various columns mean.

The cost to win a car is the minimum gold to win the car. As this is typically in the form of upgrades, this isn't added to the cost to maintain 100% and this cost is captured in the cost of upgrades.

The cost to maintain a full garage is just the reward for the special event minus the minimum gold required to win the car (i.e. this is the net cost of the car). When the car is already in the game, the purchase cost of the car, upgrades costs and series rewards are not recorded as they have already been included.

The cost to maintain 100% is the rewards for the special event and new series minus the cost of the upgrades to complete the new series. This assumes that the cost to update is always more than the cost to win but this is generally true. This isn't counting the special event twice as the cost for 100% includes the cost for winning the car. In theory I could show the delta cost on top of winning the car.

The F1 GTR is an example where it doesn't work. The upgrades and series rewards have already been counted when the car was first introduced. I guess I should show the delta cost to win the car on top of the upgrade cost but this might be confusing.
