This paper presents the results of an extended numerical experiment that continues the systematic verification of binary block algebra within the Collatz process. The study focuses on odd numbers with exactly two zero defects, covering bit-lengths from 7 to 11 bits. The experiment reveals two distinct interference regimes: concentrated paired zeros (block 00) which produce super-damping and premature collapse of trajectories, and spatially separated zeros which allow cumulative breakthroughs when the right active tail of ones exceeds a critical length (R ≥ 4). The data confirm the universality of the invariant at position k=3: structures with a right tail of exactly three ones (…0111) stop primary growth strictly at the 5th step, regardless of the number of defects. A special configuration with widely spaced zeros (number 1789) achieves the peak 1,276,936, fully inheriting the extremum of the pure Mersenne monolith M11 = 2047. The publication provides complete, unabridged data for full reproducibility. Three predictive hypotheses are formulated for multi-defect structures (m > 2), including binary filtration, soliton dynamics, and the effect of cumulative suffocation, which may lead to a general proof of boundedness of trajectories in the 3n+1 problem.
