<li>wikidatawiki: the most revisions (4x enwiki), but very few missing events (0.003% vs the 1.3% on average for all others)</li>
<li>some wikis miss more events. e.g. ukwikisource misses 34% of ~60k revisions for Feb21</li>
<li>minor edits are more likely to have missing events: 2.3% vs 0.4%</li>
<li>revision with rev_parent_id==0 are more likely to be missing (3% vs 1%). Also, events are missing for revisions with (minor_revision==true and parent_id!=0) and (minor_revision==false and parent_id==0), not for other combinations - why this strange xor behavior?</li>
<li>archived revisions are more likely to be missing (5.9% vs 1.2%), but <2% of revisions are archived</li>
<li>there are spikes in missing events when looking at hourly timeseries (for Feb21), especially for the fields (minor edit, archived, no parent id) seemingly correlated with the occurence of missing events. @joseph in a previous comment also observed bulks of missing revisions. </li>
<li>nothing stands out looking at missing events as a function of 'hour of day' / 'minute of hour'</li>
