At sea level, 1,200 cubic feet per minute (cfm) of air can carry 36,000 Btuh. However, at 5,000 feet, the thinner air carries less heat; about 1,430 cfm are needed to carry 36,000 Btuh, as will be displayed in the example below.

Altitude affects the heat dissipation capability of the heat sink and units in locations at 3300 ft (1000 m) above sea level must be derated. A common rule of thumb is a 2% derating for every 1000 ft above the 3300 ft altitude level.

Assuming the 20% de-rate, your 24000BTU outdoor unit would deliver 19200BTU and your 24000BTU indoor head would be able to deliver 19200BTU. If you combine the two, you end up with a 19200BTU system, not 40% down.
WebAltitude can have an effect--but probably from two mechanisms... One is temperature--Above ~5,000-7,000 feet, many electrical devices need power derating because there is less dense air and less cooling effect. The other is that many batteries have a pressure vent and less air pressure will let the batteries vent at low pressures.
