Acquiring new airplanes - maximum per day

[FLYAIR10]

How is it possible that some airlines are able to lease/purchase and arrange delivery  9-13 planes on one  day while I can only have 3 a day?  Has that to do with the size of the airline,or with some specific extra staff?

as per the manual....

Maximum of three (3) leases / purchases of used aircraft per game day
AND maximum of three (3) leases / purchases of used aircraft within last 7 game days.
These limits will grow when your airline becomes larger (the limits are always 3 units or at least 2% of your total fleet size; i.e. a 300-aircraft strong airline can lease / purchase up to 6 used aircraft per week).

...and my pet moan.  It's actually 3 (or however many) per EIGHT DAYS, not per week. It's a long standing bug (10+ years) which will never be fixed.
