Did not get the upgrades - a small calculation

As shown in the provided screenshots, I reviewed 7 Russian nominations between 13 and 16 June. My mean agreement percentage is 69% (nice).
The chances of not recieving an agreement out of those 7 are 0,31^7 = 0,000275 or 0,0275% (= astronomically low)
Even if only 4 of those nominations were processed before the 16th, this still puts the percentage at 0,92% - which is still very low.
Please provide further details why I did not receive the 10 upgrades and other bonuses.

I reviewed for the Russian event and I have not received any upgrades yet.
Is it possible that people who have received rewards signed up before or early into the challenge.
Anyone who signed up later will either receive the rewards later or not at all...?
I haven't received the 10 upgrades or the rewards too and I reviewed like 25+ russian nominations between 12th and 16th June. My agreement rate is approximately 67%. I come from germany and a lot of other players around here already received there upgrades and rewards...
After comparing my history of reviews in Russia to the intel map, it even shows an agreement (5* all the way for a playground, which is now a waypoint)
