Barrier XTetris Effect
Axis by axis
Execution9 vs 8
Barrier X leans harder on execution: Split-second dodges at extreme speed are the entire game
Reads0 vs 0
Even - both lean on reads about the same.
Variance2 vs 2
Even - both lean on variance about the same.
Optimization3 vs 4
Tetris Effect leans harder on optimization: Stacking theory and Zone usage have known optimal lines
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
