#5: block vs edge, one value per bounce

Start
blank tape; bounce k = the k-th time A reads the 0 just past the right end (tape then 0∞ w 1n A> 0∞)
Points
one per bounce: bounces 1..32,262 = steps 0..999,944,025 (just under 1e9)
Lines
block length n   edge width |w| (cells from the tape's left end to the block) and erosion e = cells of the block eaten during the next trip, so nnext = n + 1 − e
Block length n and edge width |w| at every bouncesame scale: the block gains about 1 cell per bounce; the edge stays thin08,00016,00024,00032,00005,00010,00015,00020,00025,00030,000bounce numberstep 1e85e81e9block n = 30,399edge |w| = 2,206First 60 bouncesthe early close call: block 0 to 2 cells020406080100102030405060bounce numbern ≤ 2n|w|Erosion per bounce: block cells the edge eats on each triporange band = min..max over each 128 bounces, orange line = their mean; blue = what the right end adds−1012468101105,00010,00015,00020,00025,00030,000bounce number+1: the right end adds one cell per bouncemean erosion +0.058 per bounce11 at bounce 13,759How often each erosion value occursall 32,261 trips; −1 = the edge gives a cell back04,0008,00012,00016,000−101234567891011cells eaten in one trip15.7k6.1k7.9k59496162359300125951
