The proposal overhauls the touchscreen star-rating system, replacing the existing flat exponential to aim star rating with a probabilistic estimation of which hand is used to hit each individual object, maintaining a list of the most likely sequences while calculating difficulty.
This is a refactored version of https://github.com/TDRework/osu/tree/touchscreen-rebalance with significantly reduced runtime.
