A separate treaty allowance for light carriers

How many light carriers might each treaty navy receive if the First London Naval Treaty created a separate category below 10,000 tons?

A separate allowance is plausible, with a suggested 100,000 tons each for Britain and the United States and 60,000 tons for Japan. An unrestricted exemption is another possibility.

Light carriers below 10,000 tons could have received either an unrestricted exemption or a separate tonnage allowance. Britain would have welcomed a category that covered escort-carrier requirements. One speculative allocation gives Britain and the United States 100,000 tons each, enough for ten ships at the category's ceiling. Japan would receive 60,000 tons under the corresponding ratio. These are suggested negotiating outcomes for the hypothetical treaty.
