The $580 figure for flights comes from the same website since there is no mention anywhere about the breakup of charges, or the formula used by Pakistan Civil Aviation to bill airlines as overflight charges. All AI are using the same slop because there is no clear info on the internet.
If you notice the Indian section on the website, it clearly mentions the formula and there is W, which means charges are proportional to the weight in some degree.

In India's case W= (MTOW/50)^1/2
The use of W is in congruence with the formula other countries use to charge airlines as well. (I checked few)
Now let's see how the $580 figure for Paxtan is obtained.
Everyone is calculating the charges in Paxtan from the same table

When it comes to navigating Pakistan airspace, understanding the air navigation charge of Pakistan, especially for overflights, is crucial. Let's delve into what air navigation charge entails and how it is calculated in Pakistan based on specific parameters.What is Air Navigation...

Lets say a Boeing 737 with MTOW of ~70 flies over Paxtan using ~1000 km airspace.
As per the table above, the charges are: 0.58 * 1000 = $580
BUT THERE IS SOMETHING MISSING in this- the W
If no W is used to calculate the overflight charges, that means a 40 MTOW and 120 MTOW pays the same flat rate of $0.58 per km, or $580 for both!
That's silly! The final overflight charges have to be proportional to the weight and not a flat rate.
So the correct formula should be: W*0.58*1000
All media are quoting the previous AI slop!
