Drag to zoom; use the toolbar to pan or reset. Dots are evaluations, not GitHub activity. Failed runs leave gaps.

Scores use hidden evaluation ratings; the input contains train + test. Accuracy is the percentage of exactly predicted ratings. These measurements support your analysis; code itself is not graded.
