Yekaterinburg Candidates - Cumulative Score

My first action after last week's post, Yekaterinburg Candidates - Fourth Week (April 2021; 'Congratulations to GM Nepomniachtchi on a well deserved victory'), was to gather the PGN for the second half of the tournament. Combining that with the PGN for the first half let me calculate the cumulative score, shown below.

The red line separates the two halves of the tournament, where the second half was played more than a year after the first. As soon as I get a chance, I'll add that image -- plus the PGN and crosstable for the second half -- to my page 2020 Candidates Tournament; Yekaterinburg (Russia).

The cumulative score continues a pattern I've noted several times on this blog. The previous mention was Yekaterinburg Candidates - First Week (March 2020):-

The eventual winner was from the group of players who had a plus score after round 3. The winner was also one of the leaders after the first half of the tournament.

That makes five consecutive candidate tournaments showing the same pattern. What are the odds?
