Why statistics on the site does not coincide with the statistics in the game?

Algorithms collection statistics IL2 stats differs from statistics in-game. As a consequence of these statistics will not coincide with the game.

How are the ratings calculated?

1) calculate how many scores player earns per one life - score / (dead + capture) = SD
2) calculate how many scores player earns per one hour - score / flight time = SH
3) calculate rating by formula: (SD * SH * score) / 1000

Note: For November 2019 we are testing a new scoring system. Details can be found on the forum.

How are coalition victories determined

1) To win a mission based on score, a coalition needs to score at least 1000 points, and at least 1.25 times the points of the opposing coalition for the win to count.
2) If a mission has a built in objective, completing this will override any victory based on score.
Much of this is based on the defaults of Vaal's statistics system. However, many of the scores have been reduced, as has the default threshold (which is 1500 points).

I landed at the airfield, but sortie status - landing not on airfield. Why?

Landing working only on active airfield. Usually active airfield is the one where you can respawn.

What is the Fairplay Index?

Fairplay Index is an indicator of the correct behavior of the player, it affects the score.The maximum value - 100% indicates that the player does not violate the rules, a player receives a 100% score and all bonuses. If the index is less than 100%, that player gets a percentage of the score corresponding to the current index. Also, in this case, the player does not receive any bonuses.
Violations of reducing the index:
Shotdown friendly aircraft -20%
Destroyed friendly ground target -5%
The index recovered by 10% per flying hour, if the player did not violate the rules.
The idea was borrowed from the project Bellum War.
