These charts are usually a day or a few days behind for individual kills. It takes time to collect statistics from the front lines, make reports and create that image overview out of it. So it’s never from events of the same day, always what recently happened.

I often saw videos of Russian columns advancing into fields and lots of wrecks at the end of the videos. Sometimes it even takes 2 days, but then there is the spike in numbers in the published data.
