The prediction of disproportionate Italian losses follows an operational principle rather than an assumption of British immunity. A fleet covering an amphibious landing must remain close enough to protect transports, bombard defenses, and sustain the assault. That obligation fixes the Regia Marina in place while Cunningham's forces retain room to maneuver and choose favorable conditions. The Royal Navy would also take losses, but the difference in operational freedom makes a disproportionate Italian defeat plausible.

An invasion fleet sacrifices freedom to maneuver
Supporting landings would pin the Regia Marina near Crete while the Royal Navy chose how and when to attack.
