get_dataset_info | Describes the Penguin Statistics drop data: what its numbers mean (times, quantity, drop rate, sanity per item, window), the game servers with their time zones and how fresh the data of each is, the caveats, the license and how to credit it. Call it when unsure how to read or cite the numbers. |
get_item_drop_rates | Returns where to farm an item on a game server: the stages that drop it, with runs (times), quantity, drop rate (items per run) and sanity per item. By default the stages open now that still drop it, lowest sanity per item first; stages of fewer than 100 runs (lowSample) rank after the others, gacha |
