The working notes retained the word "million" but omitted the table's change of units, which caused percentage figures to be read as monetary values. Most columns expressed other years relative to a 1935 baseline rather than listing pounds throughout. The transcription error does not change the broader comparison of the scale and composition of goods entering Britain or the burden those flows placed on convoy protection. Working notes need to be checked against the displayed primary source when a table changes units between columns.

A correction distinguishes the table's 1935 monetary baseline from the percentage columns used for other years without abandoning its broader point about British imports and convoy demand.
