...you are right that I failed to account for the relative difficulty in improving naturally (without the slot) in Variant 4. That is an argument in favor of the slot in Variant 4 that I missed.

Right; it is difficult to improve naturally when one is so light on building material (having already committed two checkers to the 9pt, and next aiming to make a fifth point in the blockade).

In the original position, the 10pt checkers should be treated as builders rather than as a point in the blockade, giving rise to more ways to add a fourth point to the real blockade. Without this factor, the $/U swing between the original position and Variant 4 would be greater (i.e., about what you had speculated).
