That's hardly corruption, it's just because we sucked at the time.
And it is an algorithm, and the basic formula is that more important games are worth more points.
- Friendly match x 1.00
- Continental championship preliminary x 1.50
- World Cup preliminary match x 1.50
- Continental championship finals match x 1.75
- FIFA Confederations Cup match x 1.75
- World Cup finals match x 2.00
This is why we are low, as we haven't been in a world cup in 32 years. It's also why teams like Nigeria and Mexico are so high, as they are top teams in their respective zones who gain automatic qualification spots.
