Mario Kart Tour item probability distributions
The following item probability distributions are used by Mario Kart Tour to determine the probability of obtaining a certain item when an Item Box is opened. Text directly derived from in-game data is reported in italics.
In this game the tables contain two probabilities, that are here referred to with abbreviations:
During races, the item probability distribution is chosen depending on the current position in the ranking at the moment the Item Box is opened.
Whether or not the Item Box will activate Frenzy mode will be determined first. If the player has Auto Item off, then it is not possible for them to activate Frenzy mode if a Spiny Shell, a Bullet Bill, Lightning, a Mega Mushroom, a Coin Box, Banana Barrels, a Mushroom Cannon or a Bob-omb Cannon are being hold.
The following restrictions hold for the non-Frenzy item distributions:
If items can not be obtained according to this restrictions, the corresponding percentages will be set to zero and the percentages of the other items will be scaled up such that the sum of the percentages will be unity.
Single player races (ItemSlotTable)
The following tables are for situations where Frenzy mode is not activated. There are four tables divided into two groups, whose purpose is currently unknown, although it is expected that the first table contains the probability of the first opened Item Box, while the other tables contain the probability of the following Item Boxes.
The following tables list both the probability of obtaining a Frenzy as well as the probability of obtaining a specific type of Frenzy. The first table contains the probabilities of the first lap, and the second table those of the second lap. Since only two laps are coded, it is expected that the second section of three sectioned lap either uses the first lap or second lap data.
