+This report aims to answer the questions of the KPI 11.4.
+
+1) After the proposal was executed (#1937365), how quickly did the new validators show up?  
+**It took around 10 days (05/02/2021-15/02/2021) for the number of validators to grow from 47 to 80.**
+  
+2) Was there any clear patterns for the new validators?  
+**There was a small increase from 05/02/2021 until 09/02/2021 of one or two new validators per day.   
+  Between 09/02/2021 and 10/02/2021 the number increase from from 59 to 72.
+  Until 15/02/2021 the number kept increasing by really slow.**
+
+4) Did the number of network nodes increase 'proportionally'? (Might be hard to figure out, unless you've configured your node to accept >80 peers.)  
+**Since no data was saved about the peers, the data from the active and waiting validators were used.  
+    As can been seen in the Validator Status graph the number of nodes increased drastically.  
+    By the end of 16/02/2021 already 40 nodes were in the waiting list.**
+
+5) What happened to the rewards in tJOY and USD terms?
+
+6) Was there a spike in tokens staked, or were they just shifted?
+
+7) What happened to the average block time, and blocks per era and session/epoch?
+
+8) Anything else that was noteworthy?
