I am curious about lost landings?

Here is an explanation of the system:

Landing Points Problem

Look at this calendar. [image] The Yellow Cells indicates 90 days. The red text is the number of landings on each day. If we totaled this up right now, it would be 120. (This is an example, not your real stats) You can see that there are no landings on today Jan 3rd. If we move forward to tomorrow, Jan 4th becomes yellow and October 6th turns white and “falls off”. You would then lose those 5 landings you did on 10/6 since it is now outside of the 90 days window.
