Testing collisions ( 64-bit) - Expected 0.0, actual 0 (0.00x)
Testing collisions (high 32-bit) - Expected 511.9, actual 505 (0.99x) (-6)
Testing collisions (high 24-36 bits) - Worst is 34 bits: 140/127 (1.09x)
Testing collisions (low 32-bit) - Expected 511.9, actual 497 (0.97x)
Testing collisions (low 24-36 bits) - Worst is 35 bits: 77/63 (1.20x)
