In Response To: 31S-43 — Rollout (Taper_Mike)

For theoretical interest, thanks for the 31S-43 rollout.

Splitting to the 20pt (or 18pt) is more efficient when Opp has a 10pt builder, largely because of 3 duplication. Hence, S leads the 31S-43S rollout but not the others. Another example is that 43S-41X is more efficient than 54S-41X (though in that case 5 duplication also plays a role.

51S-43 [U D7 S9 Z12 X17]
21S-43 [X Z2 S20 D21 U26]
31S-43 [S X7 D14 Z19 H48 U64]
41S-43 [X Z31 S42 D49 U60]

To spotlight the X/Z comparison, you can isolate the two plays thusly:

51S-43 [Z X5]
21S-43 [X Z2]
31S-43 [X Z12]
41S-43 [X Z31]

P.S. Yes, the Snowie 41S-43 rollout result in message 114537 is an extension of the one in message 83652.
