Cumming questions familiar victory ratios by examining how a minority of pilots accounted for a large share of claims. Acknowledged weaknesses in the evidence, small samples, and missing references leave the individual-pilot argument unproved. Including estimated Bomber and Coastal Command losses also broadens the comparison. On that basis, Cumming gives an aircraft exchange ratio of about three to two in the RAF's favour instead of two to one, and a personnel casualty ratio below two to one instead of nearly five to one. These are part of the book's disputed argument and depend on which operations and losses belong in the comparison.

How including other RAF commands changes a loss comparison
Cumming's disputed comparison changes when Bomber and Coastal Command losses enter the totals, while weaknesses in pilot-level evidence remain explicit.
