The treaty arithmetic pauses to distinguish a preferred true heavy cruiser from what negotiators of 1930 could plausibly accept. The preferred concept would displace about 16,000 tons and carry roughly 9.5-inch or 10-inch guns, a much larger design than the treaty categories under negotiation. The 10-inch option is awkward because its support demands approach those of a capital ship without delivering capital-ship levels of damage. The counterfactual therefore retains the historical 10,000-ton and eight-inch ceilings, separating an analyst's ideal design from a period-grounded settlement.

Why the alternate treaty keeps the eight-inch cruiser limit
The analysis separates a preferred 16,000-ton, 9.5- or 10-inch true heavy cruiser from the more historically plausible 10,000-ton, eight-inch treaty rule.
