My question is: how are airline scores calculated?

I have found the following categories that go into the airline score;

Pre-tax profit/loss (prev. financial quarter)

Total operating revenue (prev. financial quarter)

Profit margin (prev. financial quarter)

Company brand & image

Oldest airlines (airline age)

Airline Credit Rating

Number of weekly flights

Number of airports served

Current aircraft fleet size

Average aircraft fleet age

Average aircraft condition

Fleet utilization (avg. flt hrs / day / plane)

Departure punctuality

Available Seat Kilometres (mil. km, last 30 days)

Revenue Passenger Kilometres (mil. km, last 30 days)

Available Freight Tonne Kilometers (mil. km, last 30 days)

Revenue Freight Tonne Kilometres (mil. km, last 30 days)

Passenger Load Factor (last 30 days)

Cargo Load Factor (last 30 days)

Transported passengers (previous year)

Transported cargo (previous year)

Fuel burn per Revenue Passenger Kilometre (last 30 days)

Fuel burn per Revenue Freight Tn Kilometre (last 30 days)

The calculation method is simple. For each of the stats the maximum number of points achievable is the number of airlines in the scenario. The airlines in position #1 get this amount of points, and the last airline(s) in that stats category will get 1 point. In case of shared rankings (e.g. 3 airlines in rank #1) the shared ranks receive the same points (e.g. first three max points, and fourth will have points equalling the fourth ranking). The stats involving cargo are naturally only included if the cargo features are enabled in that particular game world.

The system also calculates a maximum achievable score value which is simply all the scores of rank #1 combined factored by *0.95. This maximum score can be seen at the airline information pages next to the actual score value. In the following image our score is 8844 and maximum possible score is 9700. (Note that in normal cases no airline can ever obtain the maximum score since the array of different statistics involved is so diverse.)

What I would like to know are all factors weighted equally and how is the actual score determined for each category?

Any help would be appreciated.
