Thank you. I'd say that is very convincing, especially with him walking about on 16, 17th and 18th.

When scanning a QR code, is the date visible anywhere on the page? I am trying to guess whether someone just edited a PDF with a different date (might explain why they chose 16.12 - you need to change a single number). Alternative would require someone back dating a test in the system.

In any case, not a good look for Djokovic.
