I don't know whether Ekstone explicitly wrote this somewhere, but as many of you know AWP is based on ATP. So, in the event that players have the same total number of points, we should follow ATP Tour rules
https://www.atptour.com/corporate/rulebook.aspxSo, here are the tie breakers:
1) the most total points from the Grand Slams, ATP World Tour Masters 1000 mandatory tournaments and Barclays ATP World Tour Finals main draws, and if still tied, then,
2) the fewest events played, counting all missed Grand Slams, ATP World Tour Masters 1000 tournaments and Barclays ATP World Tour Finals they could have played (as described under A. above) as if played, and if still tied, then,
3) the highest number of points from one single tournament, then, if needed, the second highest, and so on.
