Thanks for posting, but I don't understand where those numbers are coming from?
They have usually been released from https://www.mil.gov.ua/en/. Which AFAIK is the original source. But unfortunately that stopped working a few days ago.
I can't see the source, because it requires login?
The difference in date may be because the numbers are released up until and including the day prior to the release. So numbers released today, don't include losses from today, only up until yesterday.
