 ## Overview
 
-- **606 MIDI files** transcribed from WAV recordings via transkun
+- **2,627 MIDI files** transcribed from WAV recordings via [transkun](https://github.com/RongTongZi/transkun)
 - **13 songs** performed by student pianists
-- **Labels**: normalized instructor ratings (0-1 scale, originally 1.5-5.0)
-- **Splits**: 424 train / 91 val / 91 test (stratified)
-
-## Task
-
-Regression: given a piano performance MIDI (without reference score),
-predict a quality rating. Metrics: MSE, MAE, Pearson r, Spearman rho.
-
-## Directory Structure
-
+- **2,511 performances** with ratings from 3 expert judges (0-100 scale each)
+- **Labels**: normalized mean score to [0, 1]
+- **Splits**: 1,757 train / 377 val / 377 test (stratified by song)
