Why the counterfactual supplies no pre-Washington carrier count

How many carriers would Britain have on the eve of the Washington Naval Treaty in this scenario?

No total is given because the scenario does not expect a Washington treaty to take place.

The question assumes that the imagined British fleet will eventually reach a Washington conference. The proposed timeline instead removes that conference, so it supplies no numerical carrier total for its eve. Britain is imagined demanding a reduction in German maritime infrastructure while preserving enough of the German economy to meet its debts. The same settlement allows Germany a land army that remains relevant to the continental balance.
