How larger air groups create cumulative advantages

What difference would a somewhat larger Audacious-like British carrier have made in the Mediterranean?

It would add aircraft to Taranto and Crete and make maintenance and attrition less damaging to available strike strength.

The alternative carrier would contribute roughly sixteen to twenty-four more aircraft to major operations such as Taranto. It would also provide additional fighters for the Battle of Crete and other Mediterranean commitments. A larger air group lets commanders rotate aircraft through repair and maintenance without reducing the size of the next strike as sharply. That, in turn, can reduce cumulative losses because more serviceable aircraft are available for defense and offensive suppression. A later counterfactual adds that the survival of Glorious could strengthen the Taranto force, suppress Italian capital ships for longer, and release more British heavy units for home waters. The answer does not claim carrier availability alone changes the war's outcome, but it could alter British losses and the distribution of operational strength.
