When using RTrack Falcon, you may come across a “high uncertainty” warning on some gamepasses and their sales estimates. This is usually the case with smaller gamepasses, as even differences of a few thousand sales can cause these estimates to be much less accurate.
Roblox does not release gamepass sale data in any form, and RTrack Falcon doesn’t get the data shown from Roblox. The estimates are made using a proprietary system and a wide range of factors to estimate the sales as best as possible. These factors do not include the performance of the game itself (e.g. Visits, Players, Ratings).
