You can view your live stats by pressing on your name in the top corner followed by the (i) icon next to your grade. This will bring up your live stats. I see many posts from new IF players regarding their stats or why their landing count is dropping or general questions on how it works. (See https://community.infinite-flight.com/t/how-can-i-find-my-grade-table/147844 for more information)
Some stats are based on a period of time and are listed next to the stat themselves. For this example we will focus on the valuable landings count which shows it is for the past 90 days.
The yellow cells indicates 90 calendar days. The 90 day stats count is a “rolling” 90 day window. In the top example, on June 1st we can see that for 90 days in the past there were a total of 18 landings. March 4th was the 90th day and had 3 landings logged that day.
The bottom chart, on June 2nd since the 90 day “window” shifted, the 3 landings on March 4th dropped off. Since there were no new landings on June 2nd, the total landing count dropped from 18 to 15. It may seem simple to some but this can be confusing to many who are trying to improve their stats.
The same logic works for all other calendar based stats. If you receive a violation for speeding today, simply wait a few days and it will eventually fall off. Stay active and keep at it and your grade will hopefully improve over time.
