The example describes more than 110 ships being kept at sea from a fleet estimated at roughly 260 to 280 ships, depending on the period. It contrasts that force with 330 ships and suggests that sustaining the same output over the longer term would call for nearer 380 to 400. These figures are the discussion's estimates, rather than a fixed readiness formula. The comparison explains why increasing fleet size without enough maintenance capacity can still leave a navy overworked.

Keeping 110 ships at sea strains a much smaller supporting fleet
The US Navy provides a comparison for how sustained deployments can exceed the maintenance capacity of the overall force.
