Yes I agree for the number of sectors and landings you mention...
I am lucky if I fly (as PF) some 4 or 5 landings monthly...
I get no proficiency on 10-12 hrs long legs on autopilot.
An average B-737 or MD-80 pilot flies 40 or 50 sectors per month.
They know 40 different airports - I merely operate to a dozen airports.
